Description
The DAC7612U is a 12-bit, dual-channel, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates on a single +5V supply and provides rail-to-rail output swing, making it suitable for low-power applications.
Key features:
- 12-bit resolution with monotonic performance.
- Dual DACs in one package, reducing board space.
- Serial interface (SPI-compatible) for easy microcontroller interfacing.
- Low power consumption (typically 1.5mW).
- Fast settling time (10µs to ±0.5 LSB).
Applications include process control, automated test equipment, and portable instrumentation. The DAC7612U comes in an SOIC-16 package and includes an internal reference, simplifying design.
For more details, refer to the datasheet or TI’s product page.
