Overview
The AD5314ACPZ-REEL7 is a quad 10-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component is part of the AD5304/AD5314/AD5324 family, which includes DACs with resolutions of 8, 10, and 12 bits, respectively. The AD5314 operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes 500 μA at 3 V, making it suitable for low-power applications. It features on-chip output amplifiers that provide rail-to-rail output swing with a slew rate of 0.7 V/μs. The device is packaged in a 10-lead LFCSP (3mm x 3mm) package, enhancing its suitability for compact and power-efficient designs.
