AD4020 Datasheet (Analog Devices) - Differential SAR ADC

AD4020, Differential SAR ADC

The AD4020/AD4021/AD4022 are high accuracy, high speed, low power, 20-bit, Easy Drive, precision successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a single power supply, VDD.

The reference voltage, VREF, is applied externally and can be set independent of
