ADS8528/68 Bipolar Input ADC

Texas Instruments' ADS8528/68 contains eight low-power, 12-, 14-, or 16-bit, successive approximation register (SAR)-based analog-to-digital converters (ADCs) with true bipolar inputs. These channels are grouped in four pairs, thus allowing simultaneous high-speed signal acquisition of up to 650 kSPS.

The devices support selectable parallel or serial interface with daisy-chain capability. The programmable reference allows handling of analog input signals with amplitudes up to ±12 V. The ADS8528/68 family supports an auto-sleep mode for minimum power dissipation and has a temperature range of -40°C to +125°C.
