AD7607 8-Channel DAS with 14-Bit, Bipolar Input, Simultaneous Sampling ADC
●GENERAL DESCRIPTION
■The AD7607¹ is a 14-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS). The part contains analog input clamp protection; a second-order antialiasing filter; a track-and-hold amplifier; a 14-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 AD7607 operates from a single 5 V supply and can accommodate ±10 V and ±5 V true bipolar input signals while sampling at throughput rates of up to 200 k SPS for all channels.
■The input clamp protection circuitry can tolerate voltages of up to ±16.5 V. The AD7607 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 AD7607antialiasing filter has a 3 dB cutoff frequency of 22 kHz and provides 40 dB antialias rejection when sampling at 200 k SPS. The flexible digital filter is pin driven and can be used to simplify external filtering.
