AD7710ANZ

AD7710 is a signal conditioning ADC, this is a complete analogue front end for low frequency measurement applications. The device accepts low level signals directly from a strain gauge or transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24bit of no missing codes performance. The input signal is applied to a proprietary programmable gain front end based around an analogue 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 cutoff and settling time. It is suitable for use in weigh scales, thermocouples, process control, smart transmitters, chromatography applications.
