MAX1200/MAX1201/MAX1205 Evaluation Kits
General Description
The MAX1200/MAX1201/MAX1205 evaluation kits (EV kits) are assembled and tested PC boards that include the basic components necessary to drive either the 16-bit MAX1200 or 14-bit MAX1201/MAX1205 analog-to-digital converters (ADCs). Connectors for power supplies, analog inputs, and digital outputs simplify connections to the device. The PC board layouts are optimized for best dynamic performance. Each EV kit is fully assembled and tested, and includes a MAX1200, MAX1201, or MAX1205 (as requested) that is soldered and ready to test. o Accepts Sine or Square Clock Input o Proven PC Board Layout o Convenient Test Points Provided On-Board o Fully Assembled and Tested Surface-Mount Board

6) Turn on the EV kit's power supplies. 7) Press momentary switch SW1 to trigger self-calibration. 8) Turn on the input signal source. 9) Collect data using the logic analyzer.
Hardware Description
The MAX120x EV kit accepts a differential input signal between IN+AP and IN-AP, or it can accept a singleended (i.e., ground-referenced) input signal at IN. The PC board can also accommodate a Balun transformer at T1; however, transformer-coupling the input may degrade signal performance. U12, the MAX1200, is a 16-bit, 1Msps ADC with parallel two's complement data outputs. The MAX1201/ MAX1205 are 14-bit versions of the MAX1200. Data output signals are buffered by U1, U2, and U3 and provided at header J3 for evaluation.
_________________________Quick Start
Recommended Equipment
You will need the following equipment before you begin: * A triple-output power supply (-3V, +5V, and +7V) * A signal source, such as an HP8662A RF signal generator * Two stable precision voltage references * A low-phase-noise clock source, such as an HP8662A pulse generator, filtered by a 10MHz lowpass filter (Mini Circuits SLP-10.7). * A logic analyzer, such as an HP16500B, to collect the data The EV kit is shipped fully assembled and tested. Follow these steps to verify board operation. Do not turn on the power supply until all connections are completed. 1) Connect the power supplies to the -3V, +7V, +5V, AGND, and DGND pads. For best results, use separate analog and digital leads, connecting AGND to DGND close to the power supply's common terminal. 2) Connect a signal source to the IN or IN+AP/IN-AP inputs. If using differential inputs, common-mode voltage should be halfway between REF+ and REF-. 3) Connect the voltage references to the REF+ and REF- inputs. 4) Connect a sine-wave clock source to the CLK_SINE input. If using a square wave instead of a sine wave, connect it to the CLK_SQ input instead. 5) Turn on the logic analyzer and connect it to header J3. Configure it to receive data on the rising edge of the DAV strobe signal.
Reference Input
The MAX410 op amps designated as U8 and U9 on the EV board buffer the REF+ and REF- inputs. The MAX410 op amp designated as U7 on the EV board buffers resistor-dividers R2/R1/R3, providing a commonmode voltage level halfway between REF+ and REF-. Trim pot R1 adjusts the common-mode voltage. The op amps have a maximum total supply-voltage rating of 10V. The supply rails have been set to VSS = -3V and VCC = +7V to keep the signals well within the common-mode range of these op amps.
