AD7606-4:  4-Channel DAS with 16-Bit, Bipolar, Simultaneous Sampling ADC

Product Details

Product Status:Recommended for New Designs

The AD7606-4 is a 16-bit, 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 AD7606-4 operates 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 single supply operation, on chip filtering and high input impedance eliminates the need for driver op-amps and external bipolar supplies. The 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.


Applications
