The AD7616 DAS simplifies designs and lowers system costs by reducing the need for multiple parts in high channel count applications by integrating 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. Additionally, the device’s input structure eliminates the need for additional external protection circuits or external signal conditioning that add cost. On-chip filtering and high input impedance (1M ohm) eliminate the need for driver op-amps and external bipolar supplies. High accuracy on-chip ADCs provide a 90 dB SNR, enabling Class 0.2 measurement accuracy compliance and producing more accurate, reliable, time coherent data. Higher SNR performance of 92 dB can be achieved by using the on-chip oversampling mode.
The AD7616 DAS is suitable for a range of distribution applications such as relay protection for low-voltage distribution and feeder terminal units. The new device is also ideal for multiphase motor control and industrial instrumentation applications.
