Texas Instruments ADS8568 | Demoboard ADS8568EVM

Beschreibung

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. The programmable reference allows handling of analog input signals with amplitudes up to ±12 V.
