TLC7528

8 位，0.1us 双路 MDAC，并行输入，DSP 快速控制信号，简单微 I/F

The C, TLC7528E, and TLC7528I are dual, 8-bit, digital-to-analog converters DACs 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.

These devices operate from a 5V to 15V power supply and dissipates less than 15 mW 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.
