The AD4080 is a high-speed, low noise, low distortion, 20-bit, Easy Drive, successive approximation register (SAR) analog-to-digital converter (ADC). Maintaining high performance (signal-to-noise and distortion (SINAD) ratio > 90 dBFS) at signal frequencies in excess of 1 MHz enables the AD4080 to service a wide variety of precision, wide bandwidth data acquisition applications. Simplification of the input anti-alias filter design can be accomplished by applying over- sampling along with the integrated digital filtering and decimation to reduce noise and lower the output data rate for applications that do not require the lowest latency of the AD4080.
