The AD76061/AD7606-6/AD7606-4 are 16-bit, 8/6/4 channel, simultaneous sampling Analog-to-Digital Data Acquisition system (DAS). The parts contains analog input clamp protection, 2nd order anti-alias filter, track and hold amplifier, 16-bit charge redistribution successive approximation ADC, flexible digital filter, 2.5V reference and reference buffer and high speed serial and parallel interfaces. The AD7606/AD7606-6/AD7606-4 operate from a single 5V supply and can accommodate ± 10V and ±5V true bipolar input signals while sampling at throughput rates up to 200 kSPS for all channels. The input clamp protection circuitry can tolerate voltages up to ±16.5V. The AD7606 has 1 MO analog input impedance regardless of sampling frequency. The single supply operation, on chip filtering and high input impedance eliminates the need for driver op-amps and external bipolar supplies.
