Overview
The AD7386BCPZ-RL is a 16-bit, dual simultaneous sampling, high-speed successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC operates from a 3.0 V to 3.6 V power supply and features throughput rates of up to 4 million samples per second (MSPS). It is designed for applications requiring high-speed and precise analog-to-digital conversion, with integrated on-chip oversampling blocks to improve dynamic range and reduce noise at lower bandwidths.
