AD4020 Description
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 the supply voltage. The AD4020/AD4021/AD4022 power scales linearly with throughput.
