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 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. These devices operate from a 5V to 15V power supply and dissipates less than 15mW (typical). The 2- or 4-quadrant multiplying makes these devices 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. Refer to the typical application information in this data sheet. The TLC7528C is characterized for operation from 0 °C to +70°C. The TLC7528I is characterized for operation from −25 °C to +85°C. The TLC7528E is characterized for operation from −40°C to +85°C.
