Overview
The AD5327BRUZ-REEL, produced by Analog Devices Inc., is a quad 12-bit buffered voltage-output digital-to-analog converter (DAC) housed in a 16-lead TSSOP package. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and is designed for low power consumption, drawing 400 μA at 3 V and 500 μA at 5 V. The AD5327 features on-chip rail-to-rail output buffer amplifiers, ensuring that the outputs can swing rail-to-rail with a slew rate of 0.7 V/μs. It is compatible with various serial interface standards, including SPI, QSPI, MICROWIRE, and DSP interfaces, operating at clock rates up to 30 MHz.
