Mouser Supplies Two Types of ADI SAR ADCs
Pin compatible with AD4021/AD4022 and AD4020


Mouser Electronics announced on the 7th that it is supplying Analog Devices (ADI)'s 20-bit AD4021/AD4022 Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC).

Users can accurately capture high-frequency signals with the AD4021/AD4022 SAR ADC, which is pin-compatible with the AD4020 SAR ADC, and mitigate issues related to anti-aliasing filter design by implementing oversampling technology.

Mouser explained, “The AD4021/AD4022 is a fast and accurate low-power ADC,” adding that “through the Easy Drive feature, it reduces signal chain complexity and power consumption while supporting high channel density.”

The SPI-compatible serial user interface is compatible with 1.5, 2.5, 3, and 5V logic using a separate VIO logic power supply. Additionally, when combined with a long signal acquisition stage, the input current is reduced to 0.5uA/MSPS, eliminating the need for a dedicated ADC driver.
