The AD7609 is an 18-bit, 8-channel, simultaneous sampling analog-to-digital data acquisition system (DAS). The part contains an 18-bit charge redistribution successive approximation analog-to-digital converter (ADC).The AD7609 operates from a single 5 V supply and can accommodate ±10 V and ±5 V true bipolar differential input signals while sampling at throughput rates up to 200 kSPS for all channels. The input clamp protection circuitry can tolerate voltages up to ±16.5 V.
