Overview
The AD7934BRU-REEL, produced by Analog Devices Inc., is a high-speed, low-power, 12-bit successive approximation (SAR) analog-to-digital converter (ADC). This component operates from a single 2.7 V to 5.25 V power supply and features a throughput rate of up to 1.5 million samples per second (MSPS). It is designed with four analog input channels and a built-in channel sequencer, allowing for flexible configuration of input channels. The AD7934BRU-REEL is packaged in a 28-lead TSSOP and is suitable for a variety of applications requiring high-speed data acquisition with low power consumption.
