ADS8528 - 12-Bit 8-Channel Simultaneous-Sampling Bipolar-Input ADC

The ADS85x8 contain eight low-power, 12-, 14-, or 16-bit, successiveapproximation 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 acquisitionof 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 ±12V.

The ADS85x8 family supports an auto-sleep mode for minimum power dissipation and isavailable in both 64-pin VQFN and LQFP packages. The entire family is specified over a temperaturerange of –40°C to +125°C.
