Overview
The AD7388BCPZ-RL7, produced by Analog Devices Inc., is a 12-bit, dual, simultaneous sampling, high-speed successive approximation register (SAR) analog-to-digital converter (ADC). This component operates from a 3.0 V to 3.6 V power supply and features a throughput rate of up to 4 MSPS. It is part of the AD7386/AD7387/AD7388 family, which is known for its high performance and versatility in various applications.
The AD7388 is designed with integrated on-chip oversampling to enhance dynamic range and reduce noise at lower bandwidths. It includes a buffered internal 2.5 V reference, with the option to use an external reference up to 3.3 V. The device is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces, making it versatile for different system designs.
