11T he AIN pin presents a very high impedance dynamic load which varies with clock frequency.
12T emperature ranges are as follows: A, B Versions; –40°C to +85°C; S, T Versions; –55°C to +125°C.
13Apply after calibration at the temperature of interest. Full-scale error applies for both unipolar and bipolar input ranges.
14T otal drift over the specified temperature range since calibration at power-up at +25 °C. T his is guaranteed by design and/or characterization. Recalibration at any
temperature will remove these errors.
15In unipolar mode the offset can have a negative value (–VREF) such that the unipolar mode can mimic bipolar mode operation.
16T he specifications for input overrange and for input span apply additional constraints on the offset calibration range.
17For unipolar mode, input span is the difference between full scale and zero scale. For bipolar mode, input span is the difference between positive and negative
full-scale points. When using less than the maximum input span, the span range may be placed anywhere within the range of ±(VREF +0.1)
18All digital outputs unloaded. All digital inputs at 5 V CMOS levels.
19Applies in 0.1 Hz to 10 Hz bandwidth. PSRR at 60 Hz will exceed 120 dB due to the digital filter.
10CLKIN is stopped. All digital inputs are grounded.
Specifications subject to change without notice.

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although this device features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
