AD4020 20-Bit Precision SAR ADC

Analog Devices Inc. AD4020 20-Bit Precision SAR ADC is a low-power, low-noise, 1.8MSPS 20-Bit Precision Successive Approximation Register (SAR) Analog-to-Digital Converter. The AD4020 ADC offers ease-of-use features that lower the signal chain power, reduce signal chain complexity, and enable higher channel density. Operating using a 1.8V supply, the AD4020 ADC provides a ±VREF fully differential input range with a 2.4V to 5.1V. VREF range. In turbo mode, the AD4020 ADC consumes only 15mW at 1.8MSPS with a minimum SCK rate of 71MHz. The ADC achieves ±3.1ppm integral nonlinearity (INL). The AD4020 guarantees no missing codes at 20 bits with 100.5dB typical signal-to-noise ratio (SNR).
