General Description

The AD7762 is a high performance, 24-bit Σ-Δ analog-todigital converter (ADC).

It combines wide input bandwidth and high speed with the benefits of Σ-Δ conversion with a performance of 106 dB SNR at 625 kSPS, making it ideal for high speed data acquisition.

Wide dynamic range combined with significantly reduced antialiasing requirements simplify the design process.
