DAC53401DSGRQ1

Digital To Analog Converters Overview

The DAC53401DSGRQ1 is an automotive-grade, 10-bit buffered voltage-output digital-to-analog converter (DAC) from the DACx3401-Q1 family. It features a PMBus-compatible I2C interface and user-programmable nonvolatile memory (NVM). The device operates with a supply voltage range of 1.71 V to 5.5 V and supports standard, fast, and fast mode plus communication speeds. Key electrical specifications include ±1 LSB INL/DNL accuracy, a settling time of 8 µs at 5.5 V, and a typical power consumption of 0.5 mA. It utilizes an internal reference or VDD as a reference source.

Digital To Analog Converters Feature Summary

• AEC-Q100 qualified for automotive applications across –40°C to +125°C temperature grades.
• Integrated nonvolatile memory allows saving and recalling all register settings without software intervention.
• Supports programmable waveform generation including square, ramp, and sawtooth signals.
• Features flexible startup options configured for either high impedance or 10K-GND states.

Digital To Analog Converters Applications

• Automotive USB charge control systems
• Headlight brightness regulation
• Rear light circuit management

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Confirm the 'DSGR' package designation matches the required 8-pin WSON form factor. Ensure the ordering part number aligns with the intended tape-and-reel quantity specifications provided in the manufacturer's official documentation.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, buffered voltage output is required within an automotive environment. The 10-bit resolution provides adequate precision for general bias point generation. Consider the integrated NVM if system-level software overhead must be minimized during power cycles.

Digital To Analog Converters Part Context

This device belongs to the DACx3401-Q1 family, which includes pin-compatible variants such as the DAC43401-Q1 offering 8-bit resolution. Both devices share identical packaging and interface capabilities, allowing for design flexibility based on required resolution while maintaining consistent board layout constraints.

Digital To Analog Converters Replacement Considerations

The DAC43401-Q1 serves as a direct pin-compatible alternative within the same family, providing 8-bit resolution instead of 10-bit. Verify that the reduced resolution meets the application's accuracy requirements before substituting.
