AD7710ANZ Datasheet PDF - ADI

The AD7710ANZ is a complete analog front end signal conditioning Analog-to-digital Converter (ADC) for low frequency measurement applications. The device accepts low level signals directly from a strain gage or transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24-bit of no missing codes performance. The 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 can be programmed via the on-chip control register, allowing adjustment of the filter cut-OFF and settling time. The part features two differential analog inputs and a differential reference input. Typically, one of the channels will be used as the main channel with the second channel used as an auxiliary input to measure a second voltage periodically.
