AD7763BSVZ Description
The AD7763BSVZ high-performance, 24-bit, Σ-Δ analog-to-digital converter (ADC) combines wide input bandwidth and high speed with the benefits of Σ-Δ conversion, as well as the performance of 107 dB SNR at 625 kSPS, making it ideal for high-speed data acquisition. A wide dynamic range, combined with significantly reduced antialiasing requirements, simplifies the design process. An integrated buffer to drive the reference, a differential amplifier for signal buffering and level shifting, an over-range flag, internal gain and offset registers, and a low-pass, digital FIR filter make the AD7763BSVZ a compact, highly integrated data acquisition device requiring minimal peripheral component selection.
