A ceramic 1 nF capacitor from the A IN to AGND is necessary. Source resistance should be 750 Ω or less. 2Temperature Ranges are as follows: A, B, C Versions: –40 °C to +85°C; S Version: –55°C to +125°C. 3Applies 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 after 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.

WARNING! ESD SENSITIVE DEVICE 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. –3– AD7703 REV. D |
