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 accom-

modate ±10 V and ±5 V true bipolar input signals while sampling

at throughput rates of up to 200 kSPS 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 AD7607

antialiasing filter has a 3 dB cutoff frequency of 22 kHz and

provides 40 dB antialias rejection when sampling at 200 kSPS.

The flexible digital filter is pin driven and can be used to

simplify external filtering.

Patent pending.
