The AD7608BSTZ is a 8-channel Data Acquisition System with 18-bit bipolar input simultaneous sampling ADC. The part contains analog input clamp protection, a second-order anti-aliasing filter, a track-and-hold amplifier, a 18-bit charge redistribution, successive approximation analog-to-digital converter, a flexible digital filter, a 2.5V reference and reference buffer and high speed serial and parallel interfaces. It operates from a single 5V supply and can accommodate ±10 and ±5V true bipolar input signals while sampling at throughput rates of up to 200kSPS for all channels. The input clamp protection circuitry can tolerate voltages of up to ±16.5V. It has 1MR analog input impedance, regardless of sampling frequency. The single supply operation, on-chip filtering and high input impedance eliminate the need for driver op amps and external bipolar supplies. The anti-aliasing filter has a 3dB cutoff frequency of 22kHz and provides 40dB anti-alias rejection when sampling at 200kSPS.
