Data Sheet
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
AD7607
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.
