EVAL-AD7798EBZ Datasheet PDF - ADI

●The EVAL-AD7798EBZ is an evaluation board for AD7798 16bit, low power sigma delta ADC. The AD7798 is a complete analog front end for low frequency measurement applications. It contains three differential inputs and includes a low noise instrumentation amplifier, a reference detect and a low side power switch. Features include an update rate that can be varied from 4.17Hz to 470Hz, an onboard clock that eliminates the need for an external clock, and a Σ-Δ conversion technique that allows attainment of up to 16bits of no missing codes performance. The input signal is applied to an analog modulator, and the modulator output is processed by an on chip digital filter. The analog input channel of the AD7798 accepts analog input signals of ±VREF/gain, with a gain in the range of 1 to 128.
