ADS8548 Description
The ADS85x8 contain 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.
