The AD7617 is a 14-bit, DAS that supports dual simultaneous sampling of 16 channels. The AD7617 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 85 dB signal-to-noise ratio (SNR). Higher SNR performance can be achieved with the on-chip oversampling mode (85.3 dB for an oversampling ratio (OSR) of 2).
The input clamp protection circuitry can tolerate voltages up to ±21 V. The AD7617 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 device contains analog input clamp protection, a dual, 14-bit charge redistribution successive approximation register (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 AD7617 is serial peripheral interface (SPI)/QSPI™/DSP/MICROWIRE compatible.

Evaluation Kits (1)
The EVAL-AD7616SDZ/EVAL-AD7616-PSDZ is a single, full featured evaluation board designed to easily evaluate all features of both the AD7616 and AD7616-P analog-to-digital converters (ADCs). The evaluation board can be controlled by the EVALSDP-CB1Z via the 120-way high speed system demonstration platform (SDP-B) connector (J10). The EVAL-SDP-CB1Z SDP-B board controls the evaluation board through a USB port of a PC using the evaluation board software, which is available for download from the AD7616 and AD7616-P product pages.
Complete specifications for the AD7616 and AD7616-P devices are provided in the AD7616 and AD7616-P data sheets and should be consulted in conjunction with this user guide when using the evaluation boards. Full details on the EVAL-SDP-CB1Z are available on the SDP-B product page.
