SBAS633B – FEBRUARY 2016 – REVISED DECEMBER 2016 ADS868x 16-Bit, High-Speed, Single-Supply, SAR ADC Data Acquisition System
with Programmable, Bipolar Input Ranges
1 Features 3 Description The ADS8681, ADS8685, and ADS8689 devices
belong to a family of integrated data acquisition
system based on a successive approximation (SAR)
analog-to-digital converter (ADC). The devices
feature a high-speed, high-precision SAR ADC,
integrated analog front-end (AFE) input driver circuit,
overvoltage protection circuit up to В±20 V, and an onchip 4.096-V reference with extremely low
temperature drift. 1 16-Bit ADC with Integrated Analog Front-End
