This Technical Note describes the evaluation board for the AD7789 which is a low-power, complete analog front end for low frequency measurement applications. The device can accept low level input signals directly from a transducer and produce a serial digital output. It employs a sigma-delta conversion technique to realize up to 24 bits of no missing codes performance. The selected input signal is applied to a front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. Full data on the AD7789 is available in the AD7789 datasheet available on the AD7789 Product Page and should be consulted in conjunction with this Technical Note when using the evaluation board.
