The AD7760BSVZ is a 24-bit 100dB Sigma-Delta (Σ-Δ) ADC with on-chip buffer ideal for high speed data acquisition. It combines wide input bandwidth and high speed with the benefits of Σ-Δ conversion to achieve a performance of 100dB SNR at 2.5MSPS. Wide dynamic range combined with significantly reduced anti-aliasing 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 makes the AD7760 a compact, highly integrated data acquisition device requiring minimal peripheral component selection. The high performance ADC offers programmable decimation rates and the digital FIR filter can be adjusted if the default characteristics are not appropriate for the application. It is ideal for applications demanding high SNR without a complex front-end signal processing design.
