AD7606 8-Channel DAS with 16-Bit, Bipolar, Simultaneous Sampling ADC

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 MΩ 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. The AD7606/AD7606-6/AD7606-4 anti-alias filter has a 3 dB cut off frequency of 22 kHz and provides 40 dB anti-alias rejection when sampling at 200ksps. The flexible digital filter is pin driven, yields improvements in SNR, and reduces the 3 dB bandwidth. 1 Patent Pending Applications Power line monitoring and protection systems Multiphase Motor Control Instrumentation and control systems Multi-axis positioning systems Data Acquisition Systems
