Product Overview
The DAC53401 is a Texas Instruments voltage-output DAC for Signal_Chain designs. It belongs to the DACx3401 family and uses a buffered voltage-output digital-to-analog converter architecture. For DAC53401, the resolution is 10 bits, and the output voltage range is specified from 0 V to 5.5 V when the reference is tied to VDD.
The device supports a PMBus-compatible I2C interface covering standard, fast, and fast+ modes. It includes user-programmable NVM/EEPROM that saves and recalls all register settings, with 20000-cycle endurance over -40 °C to 85 °C and 50-year data retention at 25 °C. EEPROM write cycle time is specified as 5 ms minimum, 10 ms typical, and 15 ms maximum.
DAC53401 is supplied in an 8-pin WSON (DSG), 2.00 mm × 2.00 mm package. Recommended operating supply voltage is 1.71 V to 5.5 V, with a feature-summary range of 1.8 V to 5.5 V, and recommended ambient temperature range is -40 °C to +125 °C. Integrated functions support standalone square, ramp, and sawtooth waveform generation and preprogrammed low, medium, and high priority medical alarm tones.
