GENERAL DESCRIPTION

The AD76061/AD7606-6/AD7606-4 are 16-bit, simultaneous

sampling, analog-to-digital data acquisition systems (DAS) with

eight, six, and four channels, respectively. Each part 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/AD7606-6/AD7606-4 operate 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 200 kSPS for

all channels. The input clamp protection circuitry can tolerate

voltages up to ±16.5 V. The AD7606 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/AD7606-6/AD7606-4 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, yields

improvements in SNR, and reduces the 3 dB bandwidth.

1 Patent pending.
