AD7762BSVZ

AD7762 is a high performance, 24bit Σ-Δ analogue-to-digital converter (ADC). It combines wide input bandwidth and high speed with the benefits of Σ-Δ conversion with a pe+K19rformance making it ideal for high speed data acquisition. Wide dynamic range combined with significantly reduced antialiasing requirements simplify the design process. An integrated buffer to drive the reference, a differential amplifier for signal buffering and level shifting, an overrange flag, internal gain and offset registers, and a low-pass digital FIR filter make the AD7762 a compact, highly integrated data acquisition device requiring minimal peripheral component selection. In addition, the device offers programmable decimation rates, and the digital FIR filter can be adjusted if the default characteristics are not appropriate to the application. Typical applications include data acquisition systems, vibration analysis and instrumentation.
