Overview
The AD4682BCPZ-RL is a 16-bit, dual, simultaneous sampling, successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to convert analog signals into digital signals, facilitating processing and analysis by digital systems. The conversion process involves sampling, holding, quantization, and encoding, enabling the conversion of continuous analog signals into discrete digital signals.
The AD4682BCPZ-RL operates from a 3.0 V to 3.6 V power supply and features a throughput rate of up to 1 MSPS. It is packaged in a 16-lead LFCSP (3mm x 3mm x 0.75mm) and supports a temperature range of -40°C to +125°C.
