Specifications subject to change without notice.
CAUTION
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. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
The A
Temperature ranges are as follows: A, B Versions; –40 C to +85 C; S, T Versions; –55 C to +125 C.
Apply after calibration at the temperature of interest. Full-scale error applies for both unipolar and bipolar input ranges.
Total drift over the specified temperature range since calibration at power-up at +25 C. This is guaranteed by design and/or characterization. Recalibration at any
In unipolar mode the offset can have a negative value (–V
The specifications for input overrange and for input span apply additional constraints on the offset calibration range.
For 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
All digital outputs unloaded. All digital inputs at 5 V CMOS levels.
Applies in 0.1 Hz to 10 Hz bandwidth. PSRR at 60 Hz will exceed 120 dB due to the digital filter.
CLKIN is stopped. All digital inputs are grounded.

Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Transient currents of up to 100 mA will not cause SCR latch-up.
