Overview
The TLC7524CN is a CMOS, 8-bit, digital-to-analog converter (DAC) produced by Texas Instruments. It is designed for easy interface to most popular microprocessors and is particularly suited for applications requiring fast control signaling, such as in digital signal processing (DSP). The device operates from a single supply voltage ranging from 5V to 15V and is available in a 16-pin PDIP (N) package.
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 are known for their low power consumption, typically less than 5 mW, and high accuracy without the need for thin-film resistors or laser trimming.
