GENERAL DESCRIPTION
The functionally complete, easy-to-use ADS-CCD1201 is a 12-bit, 1.2MHz Sampling A/D Converter whose performance and production testing have been optimized for use in electronic imaging applications, particularly those employing charge coupled devices (CCD's) as their photodetectors. The ADS-CCD1201 delivers the lowest noise (400Vrms) and the best differential nonlinearity error (0.35LSB max.) of any commercially available 12-bit A/D in its speed class. It can respond to full scale input steps (from empty to full well) with less than a single count of error, and its input is immune to overvoltages that may occur due to blooming. Packaged in an industry-standard, 24-pin, ceramic DDIP, the ADS-CCD1201 requires 15V (or 12V) and +5V supplies and typically consumes 1.7 (1.4) Watts. The device is 100% production tested for all critical performance parameters and is fully specified over both the 0 to +70C and -55 to +125C operating temperature ranges. For those applications using correlated double sampling, the ADS-CCD1201 can be supplied without its internal samplePIN 1 2 3 4 5 6 7 8 9 10 11 12

Footnotes: All power supplies must be on before applying a start convert pulse. All supplies and the clock (START CONVERT) must be present during warmup periods. The device must be continuously converting during this time. There is a slight degradation in performance when using 12V supplies. Contact DATEL for availability of other input voltage ranges. A 100ns wide start convert pulse is used for all production testing.
Effective bits is equal to:
(SNR + Distortion) - 1.76 + 20 log 6.02 Full Scale Amplitude Actual Input Amplitude
This is the time required before the A/D output data is valid after the analog input is back within the specified range.
TECHNICAL NOTES
1. Obtaining fully specified performance from the ADS-CCD1201 requires careful attention to pc-card layout and power supply decoupling. The device's analog and digital ground systems are connected to each other internally. For optimal performance, tie all ground pins (14, 19, and 23) directly to a large analog ground plane beneath the package. Bypass all power supplies, as well as the REFERENCE OUTPUT (pin 21), to ground with 4.7F tantalum capacitors in parallel with 0.1F ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. If the user-installed offset and gain adjusting circuit shown in Figure 2 is used, also locate it as close to the ADS-CCD1201 as possible. 2. ADS-CCD1201 achieves its specified accuracies without external calibration. If required, the device's small initial offset and gain errors can be reduced to zero using the input circuit of Figure 2. When using this circuit, or any similar offset and gaincalibration hardware, make adjustments following warmup. To avoid interaction, always adjust offset before gain. 3. When operating the ADS-CCD1201 from 12V supplies, do not drive external circuitry with the REFERENCE OUTPUT (pin 21). The reference's accuracy and drift specifications may not be met, and loading the circuit may cause accuracy errors within the converter. 4. A passive bandpass filter is used at the input of the A/D for all production testing. 5. Applying a start pulse while a conversion is in progress (EOC = logic "1") initiates a new and inaccurate conversion cycle. Data for the interrupted and subsequent conversions will be invalid.

CALIBRATION PROCEDURE (Refer to Figures 2 and 3) Any offset and/or gain calibration procedures should not be implemented until devices are fully warmed up. To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuit of Figure 2 are guaranteed to compensate for the ADS-CCD1201's initial accuracy errors and may not be able to compensate for additional system errors.
+15V ZERO/ OFFSET ADJUST -15V SIGNAL INPUT 20k 200k 2k
For the ADS-CCD1201, offset adjusting is normally accomplished at the point where all output bits are 0's and the LSB just changes from a 0 to a 1. This digital output transition ideally occurs when the applied analog input is +1/2LSB (+1.2207mV). Gain adjusting is accomplished when all bits are 1's and the LSB just changes from a 1 to a 0. This transition ideally occurs when the analog input is at +full scale minus 1 1/2 LSB's (+9.99634V). Offset Adjust Procedure 1. Apply a train of pulses to the START CONVERT input (pin 16) so the converter is continuously converting. If using LED's on the outputs, a 200kHz conversion rate will reduce flicker. 2. Apply +1.2207mV to the ANALOG INPUT (pin 20).

3. Adjust the offset potentiometer until the output bits are 0000 0000 00000 and the LSB flickers between 0 and 1. Gain Adjust Procedure 1. Apply +9.99634V to the ANALOG INPUT (pin 20). 2. Adjust the gain potentiometer until all output bits are 1's and the LSB flickers between 1 and 0.

Figure 2. ADS-CCD1201 Calibration Circuit
All fixed resistors in Figure 2 should be metal-film types, and multi-turn potentiometers should have TCR's of 100ppm/C or less to minimize drift with temperature. In many applications, the CCD will require an offset-adjust (black balance) circuit near its output and also a gain stage, presumably with adjust capabilities, to match the output voltage of the CCD to the input range of the AID. If one is performing a "system I/O calibration" (from light in to digital out), these circuits can be used to compensate for the relatively small initial offset and gain errors of the A/D. This would eliminate the need for the circuit shown in Figure 2.

THERMAL REQUIREMENTS
All DATEL sampling A/D converters are fully characterized and specified over operating temperature (case) ranges of 0 to +70C and - 55 to +125C. All room-temperature (TA = +25C) production testing is performed without the use of heat sinks or forced-air cooling. Thermal impedance figures for each device are listed in their respective specification tables. These devices do not normally require heat sinks, however, standard precautionary design and layout procedures should be used to ensure devices do not overheat. The ground and power planes beneath the package, as well as all pcb signal runs to and from the device, should be as heavy as possible to help conduct heat away from the package. Electricallyinsulating, thermally-conductive "pads" may be installed underneath the package. Devices should be soldered to boards rather than "socketed," and of course, minimal air flow over the surface can greatly help reduce the package temperature. In more severe ambient conditions, the package/junction temperature of a given device can be reduced dramatically (typically 35%) by using one of DATEL's HS Series heat sinks. See Ordering Information for the assigned part number. See page 1-183 of the DATEL Data Acquisition Components Catalog for more information on the HS Series. Request DATEL Application Note AN-8, "Heat Sinks for DIP Data Converters,"or contact DATEL directly, for additional information.

Figure 3. Typical ADS-CCD1201 Connection Diagram
A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED's to the digital outputs and adjusting until certain LED's "flicker" equally between on and off. Other approaches employ digital comparators or microcontrollers to detect when the outputs change from one code to the next.

TIMING
The ADSCCD-1201 is an edge triggered device. A conversion is initiated by the rising edge of the start convert pulse and no additional external timing signals are required. The device does not employ "pipeline" delays to increase its throughput rate. It does not require multiple start convert pulses to bring valid digital data to its output pins.
