TLC5628CDW

TLC5628CDW Description

The TLC5628CDW from Texas Instruments is an 8-bit, 8-channel digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in a 16-SOIC package, this surface-mount DAC operates with a 5V analog/digital supply, making it compatible with standard logic levels. It features a SPI interface for seamless communication with microcontrollers or DSPs, ensuring easy integration into digital systems. With a ±1 LSB max INL/DNL and a 10µs typical settling time, it delivers reliable performance for medium-speed applications. The external reference input allows flexibility in setting the output range, while its string DAC architecture ensures monotonicity and low glitch energy.
