Overview
The AD7380BCPZ-RL7, produced by Analog Devices Inc., is a high-performance, dual simultaneous sampling, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). This device operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 million samples per second (MSPS). It is designed for applications requiring high speed, low power, and precise analog-to-digital conversion.
The AD7380 is part of a pin-compatible family that includes the 14-bit AD7381, making it versatile for various design needs. The device includes an integrated on-chip oversampling block that enhances dynamic range and reduces noise at lower bandwidths. It also features a buffered internal 2.5 V reference, with the option to use an external reference up to 3.3 V.
