DESCRIPTIO
116dB CMRR Independent of Gain Maximum Offset Voltage: 100V Maximum Offset Voltage Drift: 250nV/C - 40C to 125C Operation Rail-to-Rail Input Range Rail-to-Rail Output Swing Supply Operation: 2.7V to 5.5V MS8 Package
The LTC(R)6800 is a precision instrumentation amplifier. The CMRR is typically 116dB with a single 5V supply with any programmed gain including unity. The offset is guaranteed below 100V with a temperature drift of less than 250nV/C. The LTC6800 is easy to use; the gain is adjustable with two external resistors, like a traditional op amp. The LTC6800 uses charge balanced sampled data techniques to convert a differential input voltage into a single ended signal that is in turn amplified by a zero-drift operational amplifier. The differential inputs operate from rail-to-rail and the single ended output swings from rail-to-rail. The LTC6800 is available in an MS8 surface mount package.

Note 2: These parameters are guaranteed by design. Thermocouple effects preclude measurement of these voltage levels in high speed automatic test systems. VOS is measured to a limit determined by test equipment capability. Note 3: If the total source resistance is less than 10k, no DC errors result from the input bias currents or the mismatch of the input bias currents or the mismatch of the resistances connected to -IN and +IN. Note 4: The CMRR with a voltage gain, AV, larger than 10 is 120dB (typ).

Note 6: The power supply rejection ratio (PSRR) measurement accuracy depends on the proximity of the power supply bypass capacitor to the device under test. Because of this, the PSRR is 100% tested to relaxed limits at final test. However, their values are guaranteed by design to meet the data sheet limits. Note 7: The LTC6800H is guaranteed functional over the operating temperature range of -40C to 125C. Specifications over the -40C to 125C range (denoted by q) are assured by design and characterization but are not tested or QA sampled at these temperatures.

APPLICATIO S I FOR ATIO
Theory of Operation The LTC6800 uses an internal capacitor (CS) to sample a differential input signal riding on a DC common mode voltage (see Block Diagram). This capacitor's charge is transferred to a second internal hold capacitor (CH) translating the common mode of the input differential signal to that of the REF pin. The resulting signal is amplified by a zero-drift op amp in the noninverting configuration. The RG pin is the negative input of this op amp and allows external programmability of the DC gain. Simple filtering can be realized by using an external capacitor across the feedback resistor. Input Voltage Range The input common mode voltage range of the LTC6800 is rail-to-rail. However, the following equation limits the size of the differential input voltage: V - (V+IN - V-IN) + VREF V + - 1.3
V+IN
V-IN
8
U
where V+IN and V-IN are the voltages of the +IN and -IN pins respectively, VREF is the voltage at the REF pin and V+ is the positive supply voltage. For example, with a 3V single supply and a 0V to 100mV differential input voltage, VREF must be between 0V and 1.6V. Settling Time The sampling rate is 3kHz and the input sampling period during which CS is charged to the input differential voltage VIN is approximately 150s. First assume that on each input sampling period, CS is charged fully to VIN. Since CS = CH (= 1000pF), a change in the input will settle to N bits of accuracy at the op amp noninverting input after N clock cycles or 333s(N). The settling time at the OUT pin is also affected by the settling of the internal op amp. Since the gain bandwidth of the internal op amp is typically 200kHz, the settling time is dominated by the switched capacitor front end for gains below 100 (see Typical Performance Characteristics).

APPLICATIO S I FOR ATIO
Input Current
Whenever the differential input VIN changes, CH must be charged up to the new input voltage via CS. This results in an input charging current during each input sampling period. Eventually, CH and CS will reach VIN and, ideally, the input current would go to zero for DC inputs. In reality, there are additional parasitic capacitors which disturb the charge on CS every cycle even if VIN is a DC voltage. For example, the parasitic bottom plate capacitor on CS must be charged from the voltage on the REF pin to the voltage on the -IN pin every cycle. The resulting input charging current decays exponentially during each input sampling period with a time constant equal to RSCS. If the voltage disturbance due to these currents settles before the end of the sampling period, there will be no errors due to source resistance or the source resistance mismatch between -IN and +IN. With RS less than 10k, no DC errors occur due to this input current.
U
In the Typical Performance Characteristics section of this data sheet, there are curves showing the additional error from nonzero source resistance in the inputs. If there are no large capacitors across the inputs, the amplifier is less sensitive to source resistance and source resistance mismatch. When large capacitors are placed across the inputs, the input charging currents described above result in larger DC errors, especially with source resistor mismatches. Power Supply Bypassing The LTC6800 uses a sampled data technique and therefore contains some clocked digital circuitry. It is therefore sensitive to supply bypassing. A 0.1F ceramic capacitor must be connected between Pin 8 (V +) and Pin 4 (V -) with leads as short as possible.
