Product Summary

The AD7715AR-5 is a complete analog front end for low frequency measurement applications. The AD7715AR-5 can accept low level input signals directly from a transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 16 bits of no missing codes performance. The AD7715AR-5 input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter AD7715AR-5 can be programmed via the on-chip control register allowing adjustment of the filter cutoff and output update rate.
