DAC53701DSGT

Digital To Analog Converters Overview

The DAC53701 is a 10-bit buffered voltage-output digital-to-analog converter featuring nonvolatile memory and a PMBus-compatible I2C interface. It operates on a single supply from 1.8 V to 5.5 V with an internal reference or VDD as reference. Key specifications include ±1 LSB INL and DNL, 0.2 mA typical current consumption at 1.8 V, and a 2 mm × 2 mm 8-pin WSON package. The device supports standard, fast, and fast mode plus I2C speeds up to 1 MHz, offers programmable waveform generation, and includes a general-purpose input for hardware-triggered functions.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile memory allows saving and recalling all register settings without software.
• Supports programmable waveform generation including square, triangular, and sawtooth outputs.
• Features a general-purpose input for hardware-based function triggering independent of the processor.
• Includes preprogrammed medical-alarm tone generation modes for low, medium, and high priorities.
