Overview
The AD7801BRU-REEL7, manufactured by Analog Devices Inc., is a single, 8-bit, voltage output Digital-to-Analog Converter (DAC) designed for a wide range of applications. It operates from a single supply voltage of +2.7 V to +5.5 V, making it suitable for battery-powered and low-power systems. The DAC features an on-chip precision output buffer that allows the output to swing rail-to-rail, ensuring high accuracy and reliability. The device is available in a 20-lead TSSOP package and is known for its low power consumption, high speed parallel interface, and power-down capability.
