DAC43701DSGT

Digital To Analog Converters Overview

The DAC43701DSGT is an 8-bit, voltage-output smart digital-to-analog converter from Texas Instruments. It operates with a supply voltage range of 1.71 V to 5.5 V and supports temperatures from -40°C to +125°C. The device features a PMBus-compatible I2C interface with four address options and includes user-programmable nonvolatile memory for saving register settings. Key specifications include 1 LSB INL and DNL, programmable waveform generation (square, triangular, sawtooth), and pulse-width modulation output. It consumes 0.2 mA at 1.8 V and is housed in an 8-pin WSON package measuring 2 mm x 2 mm.

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 waveforms.
• Features a general-purpose input for hardware-based function triggering.
• Includes preprogrammed medical-alarm tone-generation modes.

Digital To Analog Converters Applications

• Oven control systems
• Ventilators
• Infusion pumps
• Anesthesia delivery systems
• Surgical equipment

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'DSGT' against the manufacturer's current datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select the DAC43701 when an 8-bit resolution is sufficient for the application. Choose this device over the DAC53701 if lower power consumption and cost are priorities. Verify that the required output voltage swing aligns with the 1.8 V to 5.5 V supply range. Confirm that the I2C interface speed matches the system controller capabilities.

Digital To Analog Converters Part Context

The DAC43701 belongs to the DACx3701 family, which also includes the 10-bit DAC53701. Both devices share pin compatibility and identical feature sets, differing only in resolution. This family is designed for low-power applications requiring smart DAC functionality such as internal references and nonvolatile memory in a compact 8-pin WSON package.

Digital To Analog Converters Replacement Considerations

The DAC53701DSGT is a pin-compatible alternative offering 10-bit resolution instead of 8-bit. No other direct substitutes are documented in the provided source material.
