DAC53401DSGTQ1

Digital To Analog Converters Overview

The DAC53401DSGTQ1 is a 10-bit, buffered voltage-output digital-to-analog converter (DAC) designed for automotive applications. It operates with a supply voltage range of 1.71 V to 5.5 V and features an internal reference or power supply as the reference source. The device supports PMBus-compatible I2C interfaces including standard, fast, and fast mode plus. Key electrical specifications include ±1 LSB INL/DNL accuracy, a typical settling time of 8 µs at full scale, and a maximum load regulation of 0.4 mV/mA. It consumes 0.5 mA in normal mode and 80 µA in power-down mode.

Digital To Analog Converters Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for temperature grade 1 operation.
• Integrated nonvolatile memory (EEPROM) allows saving and recalling all register settings without software intervention.
• Programmable waveform generation capabilities supporting square, ramp, and sawtooth waveforms.
• Pulse-width modulation (PWM) output functionality enabled via triangular waveform and feedback pin.

Digital To Analog Converters Applications

• Automotive USB charging systems
• Headlight control circuits
• Rear light management

Digital To Analog Converters Procurement Notes

Verify that the component matches the specific Q1 suffix indicating automotive qualification. Confirm the DSGT package designation corresponds to the 8-pin WSON form factor. Ensure the datasheet revision aligns with current production data before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when a 10-bit resolution is required for automotive environments. Consider the internal reference option if external precision references are unavailable. Evaluate the tiny 2 mm x 2 mm footprint against available PCB space constraints.

Digital To Analog Converters Part Context

This part belongs to the DACx3401-Q1 family, which includes the 8-bit DAC43401-Q1 variant. Both devices share identical pinouts and feature sets, differing only in resolution. They are engineered for low-power, space-constrained automotive designs requiring smart DAC functionalities.

Digital To Analog Converters Replacement Considerations

The DAC43401-Q1 serves as a direct pin-compatible alternative offering 8-bit resolution instead of 10-bit. Verify that the reduced resolution meets the system's accuracy requirements before substituting.

Digital To Analog Converters FAQ

What interface modes does the DAC53401-Q1 support?

The device supports I2C standard mode (100 kbps), fast mode (400 kbps), and fast mode plus (1 Mbps). It also implements specific PMBus commands.

How is the address configured on the DAC53401-Q1?

Four slave address options are available, configured by connecting the A0 pin to either the supply voltage or ground.

What is the purpose of the CAP pin?

The CAP pin requires an external capacitor ranging from 0.5 µF to 15 µF connected between it and AGND to stabilize the internal LDO.
