The AD7606-EP is a 16-bit, simultaneous sampling, analog-to-digital, data acquisition system (DAS) with eight channels. The device contains analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge redistribution successive approximation analog-to-digital converter (ADC), a flexible digital filter, a 2.5 V reference and reference buffer, and high speed serial and parallel interfaces.

The AD7606-EP operates from a single +5 V supply and can accommodate ±10 V and ±5 V true bipolar input signals while sampling at throughput rates up to 150 kSPS for all channels.

The input clamp protection circuitry can tolerate voltages up to ±16.5 V. The AD7606-EP has 1 MΩ 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 AD7606-EP antialiasing filter has a 3 dB cutoff frequency of 23 kHz. The flexible digital filter is pin driven, yields improvements in SNR,and reduces the 3 dB bandwidth.
