Introduction
The ADS8694 and ADS8698 are 4-channel and 8-channel integrated data acquisition systems based on 18-bit successive approximation register (SAR) analog-to-digital converters (ADCs), with an operating throughput of up to 500 kSPS. These devices feature an integrated analog front-end circuit for each input channel (with overvoltage protection up to ±20V), a 4-channel or 8-channel multiplexer supporting both automatic and manual scan modes, and an on-chip 4.096V reference voltage with low temperature drift. These devices are powered by a single 5V analog supply, and each input channel can support true bipolar input ranges (±10.24V, ±5.12V, and ±2.56V) and unipolar input ranges (0V to 10.24V and 0V to 5.12V). The gain of the analog front-end is precisely adjusted across all input ranges to ensure high DC accuracy. The input range can be selected through software programming, and the input range selection for each channel is independent. The device provides a constant resistive input impedance of 1MΩ (regardless of the selected input range). The ADS8694 and ADS8698 offer a simple serial interface compatible with the Serial Peripheral Interface (SPI) for the digital host and support daisy-chaining multiple devices. The digital power supply can provide voltages in the range of 1.65V to 5.25V, enabling direct connection to various host controllers.
