The TLV5618A is a high-performance, dual 12-bit Digital-to-Analog Converter (DAC) designed by Texas Instruments. It is a versatile component that converts digital signals into precise analog voltages, making it ideal for projects requiring fine control over electronic outputs. Features low-power 2.7V-5.5V operation, SPI interface, and programmable speed. Perfect for precision control.
Description
The TLV5618A is a sophisticated dual 12-bit voltage output DAC featuring a flexible 3-wire serial interface. This interface is fully compatible with popular communication protocols like SPI, QSPI, and Microwire, making it easy to integrate with microcontrollers such as Arduino, STM32, or TMS320 DSPs.
One of its standout features is the programmable settling time, which allows you to switch between "Fast Mode" for high-speed response and "Slow Mode" to conserve battery power. The device includes an internal rail-to-rail output buffer that doubles the reference voltage, ensuring a wide and stable output range. Whether you are building an industrial controller or a high-fidelity audio signal generator, the TLV5618A provides the precision and reliability needed for professional-grade electronics.
Features
Dual 12-Bit Outputs: Two independent channels (DAC A and DAC B) in a single small package.
Programmable Speed: Choose between 3 µs (Fast Mode) or 10 µs (Slow Mode) to balance performance and power.
Wide Supply Range: Operates on any voltage from 2.7V to 5.5V, suitable for both 3.3V and 5V logic systems.
Flexible Serial Interface: Simple 3-wire SPI-compatible interface for easy programming.
Low Power Consumption: Includes a power-down mode that reduces current to just 1 µA.
Rail-to-Rail Output: Integrated buffer provides a stable output voltage up to the power supply rails.
Applications
Digital Servo Control: Precise positioning in robotics and automation.
Industrial Process Control: Tuning and calibration of factory machinery.
Motion Control: Controlling motors and actuators with high accuracy.
Mass Storage Devices: Managing head positioning and electronic adjustments.
Battery-Powered Instruments: Ideal for portable gear thanks to its low-power modes.
