The AD7763 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 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 ampli-fier for signal buffering and level shifting, an overrange flag, internal gain and offset registers, and a low-pass, digital FIR filter make the AD7763 a compact, highly integrated data acquisition device requiring minimal peripheral component selection. In addition, the device offers programmable decimation rates and a digital FIR filter, which can be user-programmed to ensure that its characteristics are tailored for the user’s application. The AD7763 is ideal for applications demanding high SNR without necessitating the design of complex, front-end signal processing.
