DAC7574IDGS

Digital To Analog Converters Overview

The DAC7574IDGS is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an I2C-compatible serial interface for data input and control. The device operates with a single analog supply voltage ranging from 2.7 V to 5.5 V and a separate digital supply voltage of the same range. It utilizes a 10-pin VSSOP package and supports an operating temperature range from -40°C to +85°C. The component integrates internal reference options and provides buffered voltage outputs for each channel.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required pin configuration and electrical specifications. Cross-reference the manufacturer's latest documentation to validate RoHS compliance and lifecycle status before procurement.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit voltage outputs are required within a space-constrained design. The I2C interface simplifies PCB routing compared to parallel or SPI alternatives. Verify that the system supply voltage aligns with the 2.7 V to 5.5 V operational range. Consider the thermal performance within the specified industrial temperature limits during layout.

Digital To Analog Converters Part Context

This component belongs to the DAC757x family of quad 12-bit DACs from Texas Instruments. It shares architectural similarities with other members like the DAC7571 and DAC7572, differing primarily in resolution and channel count. The IDGS suffix denotes the industrial temperature range and the 10-pin VSSOP package style used for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC7571IDGS and DAC7572IDGS from the same family. These parts offer similar packaging and interface compatibility but differ in resolution or channel count. Verify pinout compatibility and electrical parameter alignment before substitution.
