AD4080: 20-bit, 40 MSPS, Differential SAR ADC

The AD4080 is a high-speed, low-noise, low-distortion 20-bit, Easy Drive successive approximation register (SAR) analog-to-digital converter (ADC).
The AD4080 maintains high performance (signal-to-noise and distortion (SINAD) ratio > 90 dBFS) at signal frequencies above 1 MHz, enabling it to address a variety of precision, wide-bandwidth data acquisition applications. For applications that do not require the AD4080's lowest latency, oversampling can be applied, along with on-chip digital FILTERS and decimation, to simplify input antialiasing FILTERS design, reduce noise, and lower output data rates.
