Overview
The AD5314ARMZ-REEL7 is a quad 10-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and consumes 500 μA at 3 V. It is packaged in a 10-lead MSOP and is designed for applications requiring high precision and low power consumption.
The AD5314 features on-chip output amplifiers that allow for rail-to-rail output swing with a slew rate of 0.7 V/μs. The device uses a 3-wire serial interface compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards, operating at clock rates up to 30 MHz.
