Texas Instruments DACx3401 Digital-to-Analog Converters (DACS) are a pin-compatible family of buffered voltage-output DACs. These devices consume very low power and are available in a tiny 8-pin WSON package.
The feature set combined in this tiny package and low power makes the device an attractive choice for applications including LED and general-purpose bias point generation, digitisers, PWM signal generation, power supply control, and medical alarm tone generation.
These devices have non-volatile memory, an internal reference, and a PMBus-compatible I2C interface. The device functions with either an internal reference or the power supply as a reference and offers a full-scale output of 1.8V to 5.5V. The devices communicate through the I2C interface. These DACS support I2C standard mode, fast mode, and fast+ mode.
The devices are feature-rich and comprise PMBus voltage margin commands, user-programmable power up to high impedance, medical alarm tone generator, standalone waveform generator, dedicated feedback pin, and more.
