BU3616K

Digital To Analog Converters Overview

The BU3616K is a CMOS-based, high-speed, low-power 3-channel 8-bit digital-to-analog converter (DAC) manufactured by ROHM Semiconductor. It integrates an internal reference voltage source, eliminating the need for external references. The device features current outputs for Red, Green, and Blue channels, supporting TTL input logic. Recommended operating conditions specify DVDD and AVDD voltages between 4.5V and 5.5V. Key electrical characteristics include a typical current dissipation of 15mA, a full-scale voltage of 1.44V at 5.0V supplies, and a settling time of 40ns with a 15pF load. It operates within a temperature range of -10°C to +70°C.
