Overview
The TLC7524CPWR is a CMOS, 8-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device is designed for easy interface with most popular microprocessors and is particularly suited for applications requiring fast control signaling, such as in digital signal processing (DSP) and microprocessor-controlled gain-setting and signal-control scenarios.
The TLC7524 series includes the TLC7524C, TLC7524E, and TLC7524I, each characterized for different operating temperature ranges: 0°C to 70°C for the TLC7524C, -40°C to 85°C for the TLC7524E, and -25°C to 85°C for the TLC7524I. These devices operate from a single supply voltage of 5V to 15V and are available in a TSSOP-16 package.
