1 pcs : ADS8694IDBT - Analog to Digital Converters - ADC 18-Bit 500kSPS 4-Channel SAR ADC With Bipolar Inputs Off 5V Supply 38-T

ADS869x 18-Bit SAR Analog-to-Digital Converters Texas Instruments ADS869x 18-Bit SAR Analog-to-Digital Converters (ADCs) are 4- and 8-channel, integrated data acquisition systems based on a 18-bit successive approximation (SAR) ADC. Each operates at a throughput of 500kSPS. These devices feature integrated analog front-end circuitry for each input channel with overvoltage protection up to ±20V. They also include a 4- or 8-channel multiplexer with automatic and manual scanning modes, and an on-chip, 4.096V reference with low-temperature drift. Operating on a single 5V analog supply, each input channel on the devices can support true bipolar input ranges of ±10.24V, ±5.12V, ±2.56V. They can also support unipolar input ranges of 0V to 10.24V and 0V to 5.12V. The gain of the analog front-end for all input ranges are accurately trimmed to ensure a high dc precision. The input range selection is software-programmable and independent for each channel.
