Overview
The AD7383BCPZ-RL is a 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is part of a family of dual simultaneous sampling, high-speed, low-power successive approximation register (SAR) ADCs. It operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS. The AD7383BCPZ-RL is designed to convert analog signals into digital signals, facilitating processing and analysis by digital systems through steps such as sampling, holding, quantization, and encoding.
