NOTES
1The A
IN pin presents a very high impedance dynamic load that varies with clock frequency.
2Temperature ranges are as follows: A, B Versions: –40
°C to +85°C; S, T Versions: –55°C to +125°C.
3Apply after calibration at the temperature of interest. Full-scale error applies for both unipolar and bipolar input ranges.
4Total 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 temperature will remove these errors.
5In Unipolar mode, the offset can have a negative value (–V
REF) such that the Unipolar mode can mimic Bipolar mode operation.
6The specifications for input overrange and for input span apply additional constraints on the offset calibration range.
7For 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
±(V
REF +0.1).
8All digital outputs unloaded. All digital inputs at 5 V CMOS levels.
9Applies 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.
