TLC5615CD

TLC5615CD Description

The TLC5615CD from Texas Instruments is a 10-bit digital-to-analog converter (DAC) designed for precision voltage output applications. Housed in an 8-pin SOIC package, this surface-mount IC operates with a single 5V supply for both analog and digital domains, simplifying power management. It features an SPI-compatible serial interface, enabling seamless integration with microcontrollers and digital systems. With a ±1 LSB maximum integral nonlinearity (INL) and ±0.1 LSB differential nonlinearity (DNL), it delivers high accuracy for low-to-mid-speed applications. The 12.5µs typical settling time ensures rapid response in dynamic systems.
