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

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
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.
