Overview
The AD7380BCPZ-RL is a 16-bit, dual simultaneous sampling, high-speed, low-power successive approximation register (SAR) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a 3.0 V to 3.6 V power supply and features throughput rates up to 4 MSPS. It is part of the AD7380/AD7381 family, which includes both 16-bit and 14-bit versions, ensuring pin compatibility across the range.
The AD7380BCPZ-RL is designed for high-performance applications, offering differential analog inputs with a wide common-mode range and an integrated on-chip oversampling block to enhance dynamic range and reduce noise at lower bandwidths. The device includes a buffered internal 2.5 V reference, with the option to use an external reference up to 3.3 V.
