AD7606

The AD7606 is a 16-bit, 8-channel simultaneous-sampling analog-to-digital converter from ADI that integrates eight ADCs, an input clamp, an analog input amplifier, a second-order anti-alias filter, an on-chip reference and a flexible digital interface in one package. Each channel has a signal-to-noise ratio and a total harmonic distortion that suit a power-quality meter or a protection relay, and the true differential inputs operate over several bipolar ranges, so a designer can measure a high-voltage signal without a wide external network. Because all eight channels capture at the same instant, the AD7606 preserves the phase relationship between a voltage and a current channel, which a multiplexed converter cannot do. The device runs from a single 5 V supply with a configurable input range and provides a parallel and a serial interface, so it connects to a host with a modest amount of logic. The on-chip reference plus the internal filter remove several external parts and simplify the analog front end. Typical applications include a power-line meter, a power-quality analyzer, a protection relay, a multi-axis control loop and any system that must sample many channels coherently. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the input range and the interface and plan the reference and the layout.
