1 pcs : ADS8671IPW - Analog to Digital Converters - ADC 14-Bit, 1-MSPS, 1-Ch SAR ADC with programmable (+/-12/+/-10/+/-6/+/-5/+/

ADS8671/ADS8675 SAR Analog-to-Digital Converters Texas Instruments ADS8671/ADS8675 SAR Analog-to-Digital Converters (ADCs) are integrated data acquisition system based on a successive approximation (SAR) ADCs. The devices feature a high-speed, high-precision SAR ADC, integrated analog front-end (AFE) input driver circuit. They also include overvoltage protection circuit up to ±20V and an on-chip 4.096V reference with extremely low-temperature drift. The devices operate on a single 5V analog supply but support true bipolar input ranges of ±12.288V, ±6.144V, ±10.24V, ±5.12V, and ±2.56V. They also support unipolar input ranges of 0V to 12.288V, 0V to 10.24V, 0V to 6.144V, and 0V to 5.12V. The gain and offset errors are accurately trimmed within the specified values for each input range to ensure high dc precision. The input range selection is done by software programming of the device internal registers. The devices offer a high resistive input impedance (≥ 1MΩ) irrespective of the selected input range.
