TLC7528CN

The TLC7528CN is a dual 8-bit Digital-to-analog Converter (DAC) designed with separate on-chip data latches and feature exceptionally close DAC-to-DAC matching. Data is transferred to either of the two DAC data latches through a common, 8-bit, input port. Control input DACA/DACB determines which DAC is to be loaded. The load cycle of these devices is similar to the write cycle of a random-access memory, allowing easy interface to most popular microprocessor buses and output ports. Segmenting the high-order bits minimizes glitches during changes in the most significant bits, where glitch impulse is typically the strongest. This device operates from a 5 to 15V power supply and dissipates less than 15mW. The 2 or 4-quadrant multiplying makes this device a sound choice for many microprocessor-controlled gain-setting and signal-control applications. It can be operated in voltage mode, which produces a voltage output rather than a current output.
