AD7760(RevPrN) Datasheet PDF - Analog Devices

PRODUCT OVERVIEW
The AD7760 high performance 20-bit sigma delta analog to digital converter combines wide input bandwidth and high speed with the benefits of sigma delta conversion with performance of 100dB SNR at 2.5MSPS making it ideal for high speed data acquisition. Wide dynamic range combined with significantly reduced anti-aliasing requirements simplify the design process.
