The AD76061/AD7606-6/AD7606-4 are 16-bit, 8/6/4 channel, simultaneous sampling Analog-to-Digital Data Acquisition
system (DAS). The parts contains analog input clamp protection,
2nd order anti-alias filter, track and hold amplifier, 16-bit charge
redistribution successive approximation ADC, flexible digital
filter, 2.5V reference and reference buffer and high speed serial
and parallel interfaces.
The AD7606/AD7606-6/AD7606-4 operate from a single 5V
supply and can accommodate ± 10V and ±5V 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 ±16.5V. The AD7606 has 1 MO analog input
impedance regardless of sampling frequency. The single supply
operation, on chip filtering and high input impedance eliminates
the need for driver op-amps and external bipolar supplies. The
AD7606/AD7606-6/AD7606-4 anti-alias filter has a 3 dB cut off
frequency of 22 kHz and provides 40 dB anti-alias rejection when
sampling at 200ksps. The flexible digital filter is pin driven, yields
improvements in SNR, and reduces the 3 dB bandwidth.
