Overview
The TLC7528CFN, produced by Texas Instruments, is a dual 8-bit multiplying digital-to-analog converter (DAC). This device is designed with separate on-chip data latches and features exceptionally close DAC-to-DAC matching. It operates from a 5V to 15V power supply and is suitable for various microprocessor-controlled applications, including gain-setting and signal control. The TLC7528CFN is characterized for operation in different temperature ranges depending on the variant (TLC7528C: 0°C to +70°C, TLC7528I: −25°C to +85°C, TLC7528E: −40°C to +85°C).
