Overview
The AD5328BRU-REEL7, produced by Analog Devices Inc., is an octal 12-bit buffered voltage output Digital-to-Analog Converter (DAC) packaged in a 16-lead TSSOP. This device operates from a single supply voltage ranging from 2.5 V to 5.5 V and is designed for low power consumption, typically 0.7 mA at 3 V. The AD5328 features on-chip rail-to-rail output buffer amplifiers, ensuring a wide output voltage range and a slew rate of 0.7 V/μs. It is highly versatile, supporting various serial interface standards including SPI, QSPI, MICROWIRE, and DSP, with clock rates up to 30 MHz.
