TLC5628CDWR

TLC5628CDWR Description

The TLC5628CDWR from Texas Instruments is an 8-bit, 8-channel digital-to-analog converter (DAC) with voltage output, designed for precision analog signal generation. Packaged in a 16-SOIC surface-mount form factor, it operates over a 0°C to 70°C temperature range and is RoHS3 compliant, making it suitable for environmentally conscious designs. The device features an SPI-compatible serial interface, simplifying integration with microcontrollers and digital systems. With a ±1 LSB max INL/DNL and a 10µs typical settling time, it delivers reliable performance for medium-speed applications. The DAC requires a 5V analog and digital supply, supporting an external reference for flexible voltage scaling.
