DAC43401DSGRQ1

Digital To Analog Converters Overview

The DAC43401DSGRQ1 is an automotive-grade, 8-bit buffered voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates within a supply voltage range of 1.71 V to 5.5 V and supports I2C standard, fast, and fast mode plus interfaces. The device features a 1 LSB INL/DNL accuracy, internal reference options, and user-programmable nonvolatile memory for register retention. It provides flexible startup configurations and digital slew-rate control in an 8-pin WSON package.

• AEC-Q100 qualified for automotive applications with extended temperature support
• PMBus compatible I2C interface with multiple slave address options
• Integrated nonvolatile memory for saving and recalling register settings
• Programmable waveform generation including square, ramp, and sawtooth outputs

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 Grade 1 requirements for your target operating temperature range. Cross-reference the datasheet revision history to confirm compatibility with your system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when an automotive-rated, low-power DAC with integrated nonvolatile memory is required. It is suitable for designs needing programmable waveform generation or force-sense output capabilities without external software intervention. Consider the 8-bit resolution and I2C interface speed requirements relative to your system's data throughput needs.

Digital To Analog Converters Part Context

This part belongs to the DACx3401-Q1 family, which includes pin-compatible 10-bit variants like the DAC53401-Q1. The family shares identical packaging and interface characteristics but differs in resolution. The Q1 suffix specifically denotes automotive qualification, distinguishing it from commercial grade counterparts that may lack extended temperature ranges or reliability certifications.

Digital To Analog Converters Replacement Considerations

The DAC43401DSGT is a listed substitute offering identical functional specifications and pinout compatibility. Verify that the alternative package variant maintains the same thermal performance and mechanical dimensions for your PCB layout.
