DAC539G2WRTERQ1

Digital To Analog Converters Overview

The DAC539G2WRTERQ1 is an automotive-grade, application-specific smart digital-to-analog converter designed for general-purpose input (GPI) to pulse-width-modulation (PWM) conversion. It features a 10-bit resolution with 1 LSB differential nonlinearity and operates within a supply voltage range of 1.8 V to 5.5 V across a temperature range of –40°C to +125°C. The device integrates a look-up table (LUT) that maps three GPIs to eight 10-bit digital codes representing voltage outputs. It supports both I2C and SPI interfaces with automatic detection, user-programmable nonvolatile memory (NVM), and internal or external reference options.

Digital To Analog Converters Feature Summary

• Triple general-purpose inputs mapped via look-up table to generate 10-bit voltage outputs
• Voltage-to-PWM converter utilizing programmable sawtooth or triangular waveforms
• Automatic detection of I2C and SPI communication protocols without hardware configuration
• User-programmable nonvolatile memory for storing look-up table values

Digital To Analog Converters Applications

• Rear light systems in automotive applications
• Condition monitoring modules
• Wired control systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'RTE' corresponds to the 16-pin WQFN package with wettable flanks as documented in the datasheet. Confirm AEC-Q100 Grade 1 qualification requirements are met for the intended automotive environment. Ensure the design accommodates the 3 mm × 3 mm package dimensions and thermal pad grounding requirements specified in the mechanical data.

Digital To Analog Converters Selection Notes

Select this component when a direct GPI-to-PWM conversion function is required without external microcontroller processing. The device is suitable for designs needing integrated fault communication capabilities in lighting circuits. Consider the 10-bit resolution and single-channel voltage output if precise analog control is not the primary requirement compared to the PWM generation capability.

Digital To Analog Converters Part Context

The DAC539G2-Q1 series includes variants such as the standard RTE package and the wettable flank version. This specific part number represents the Texas Instruments automotive-qualified smart DAC optimized for converting digital inputs directly into PWM signals using internal lookup tables, distinguishing it from standard multi-channel DACs by its specialized GPI-to-PWM architecture.
