描述 Description

The TLC7628C is a dual, 8-bit, digital-to-analog converter (DAC) designed with separate on-chip data latches and featuring exceptionally close DAC-to-DAC matching. Data are transferred to either of the two DAC data latches through a common, 8-bit input port. Control input DACA/DACB determines which DAC is loaded. The load cycle of this device 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.
The TLC7628C operates from a 10.8-V to 15.75-V power supply and is TTL-compatible over this range. 2- or 4-quadrant multiplying makes these devices a sound choice for many microprocessor-controlled gain-setting and signal-control applications.
The TLC7628C is characterized for operation from 0°C to 70°C.
