The AD7616 is a 16-bit, DAS that supports dual simultaneous sampling of 16 channels. The AD7616 operates from a single 5 V supply and can accommodate ±10 V, ±5 V, and ±2.5 V true bipolar input signals while sampling at throughput rates up to 1 MSPS per channel pair with 90.5 dB SNR. Higher SNR performance can be achieved with the on-chip oversampling mode (92 dB for an oversampling ratio (OSR) of 2).
The input clamp protection circuitry can tolerate voltages up to ±21 V. The AD7616 has 1 MÙ 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 device contains analog input clamp protection, a dual, 16-bit charge redistribution SAR 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 AD7616 is serial peripheral interface (SPI)/QSPI™/DSP/ MICROWIRE compatible
