DAC539E4YBHR

Digital To Analog Converters Overview

The DAC539E4YBHR is a quad-channel, 10-bit smart digital-to-analog converter (DAC) designed for standalone fault management. It integrates four programmable comparator inputs and four general-purpose outputs (GPOs), linked via a look-up table (LUT). The device supports I2C and SPI interfaces with automatic detection and operates on a supply voltage ranging from 1.7 V to 5.5 V. Key electrical specifications include a differential nonlinearity (DNL) of ±1 LSB and an integral nonlinearity (INL) of ±1.25 LSB. It features user-programmable nonvolatile memory (NVM) for processor-less operation and includes an internal reference.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix YBHR corresponds to the DSBGA-16 package configuration. Confirm that the required operating temperature range aligns with the specified -40°C to +125°C limits. Ensure the design accommodates the external capacitor requirements for the CAP pin to maintain stable internal LDO performance during operation.

Digital To Analog Converters Selection Notes

Select this component when a compact solution for autonomous fault monitoring is required without a central processor. The integrated LUT allows complex logic mapping between analog thresholds and digital outputs. Verify that the 10-bit resolution meets the precision needs for the specific application's threshold detection requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC539E4W series, which focuses on smart DAC applications requiring minimal external control. The YBH suffix identifies the specific 16-pin DSBGA package variant. This series is engineered to reduce system complexity by integrating comparators and output drivers directly alongside the DAC cores.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other variants of the DAC539E4W series. Verify package compatibility and pin assignments before substitution. Cross-referencing with similar Texas Instruments smart DAC products may be necessary if specific gain configurations differ.
