Overview
The AD5328BRU, produced by Analog Devices Inc., is an octal 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, making it versatile for various applications. It features low power consumption, with a typical current of 0.7 mA at 3 V, and includes on-chip rail-to-rail output buffer amplifiers that provide a slew rate of 0.7 V/μs. The AD5328BRU is designed for high accuracy and reliability, with guaranteed monotonicity over all codes and a power-down mode to minimize power usage.
