AD7764BRUZ

AD7764 is a high performance, 24bit, sigma-delta (Σ-Δ) analogue-to-digital converter (ADC). It combines wide input bandwidth, high speed, and performance of 109dB dynamic range at a 312.5KHz output data rate. With excellent dc specifications, the converter is ideal for high speed data acquisition of ac signals where dc data is also required. Using the AD7764 eases front-end antialias filtering requirements, simplifying the design process significantly. The AD7764 offers pin-selectable decimation rates of 64×, 128× and 256×. Other features include an integrated buffer to drive the reference, as well as a fully differential amplifier to buffer and level shift the input to the modulator. Typical application include data acquisition systems, vibration analysis and instrumentation.
