Overview
The DAC7573IPWR from Texas Instruments is a quad-channel, 12-bit digital-to-analog converter (DAC) designed for low-power applications. It features a micropower operation with a current consumption of 600 µA at 5 V and supports an I2C compatible two-wire serial interface. The device includes an on-chip precision output amplifier that allows for rail-to-rail output swing and is suitable for use in a wide range of temperatures from -40°C to 105°C. This DAC is particularly useful in portable battery-operated equipment due to its low power consumption and compact 16-lead TSSOP package.
