Overview
The TLC7528CNSR, produced by Texas Instruments, is a dual 8-bit digital-to-analog converter (DAC) designed for high-performance applications. This device features separate on-chip data latches and exceptionally close DAC-to-DAC matching, making it ideal for microprocessor-controlled gain-setting and signal-control applications. The TLC7528CNSR operates in voltage mode, producing a voltage output rather than a current output, and is compatible with various microprocessor buses and output ports due to its similar load cycle to the write cycle of a random-access memory.
