The ADS8661Wis an integrated data acquisition system based on a successive approximation (SAR) analog-to-digital
converter (ADC) topology. The device features a high-speed,
high-precision SAR ADC, integrated differential analog front-end (AFE) input driver
circuit. The ADS8661W includes an overvoltage
protection circuit up to ±20V and an on-chip 4.096V reference with extremely low
temperature drift.
The device operates on a single
5V analog supply, but support true bipolar input ranges and unipolar input ranges.
The bipolar input ranges are ±12.288V, ±6.144V, ±10.24V, ±5.12V, and ±2.56V, and the
unipolar input ranges are from 0V to 12.288V, 10.24V, 6.144V, and 5.12V. The devices offer a high resistive input impedance (≥ 1MΩ)
irrespective of the selected input range.
The multiSPI digital interface is
backward-compatible to the traditional SPI protocol. Additionally, configurable
features simplify interface to a wide range of host controllers.
