SBAS780 – DECEMBER 2016 ADS866x 12-Bit, High-Speed, Single-Supply, SAR ADC Data Acquisition System
with Programmable, Bipolar Input Ranges
1 Features 3 Description The ADS8661 and ADS8665 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 on-chip 4.096-V reference
with extremely low temperature drift. 1 12-Bit ADC with Integrated Analog Front-End
High Speed:
– ADS8661: 1.25 MSPS
– ADS8665: 500 kSPS
Software Programmable Input Ranges:
– Bipolar Ranges: ±12.288 V, ±10.24 V,
В±6.144 V, В±5.12 V, and В±2.56 V …
