DAC7574IDGSRG4

Digital To Analog Converters Overview

The DAC7574IDGSRG4 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 on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital domains. It utilizes a resistor-string architecture with buffered voltage outputs. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels within a single compact package.
• Utilizes a standard two-wire I2C serial interface for simplified system connectivity.
• Provides buffered voltage outputs capable of driving moderate loads directly.
• Operates efficiently across a wide single-supply voltage range.

Digital To Analog Converters Applications

• Portable instrumentation systems requiring multi-channel signal generation
• Battery-powered devices due to low power consumption characteristics
• Industrial process control loops needing precise analog output levels
• Programmable gain amplifier reference voltage sources

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments standards. Confirm the package type matches the design footprint requirements. Ensure the I2C address configuration aligns with the system bus topology. Check for any specific ordering prefixes that may affect availability or documentation versions.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution analog outputs are required in space-constrained designs. It serves as a suitable alternative to higher-resolution single-channel DACs when channel count is prioritized over precision. Consider the 12-bit resolution limits for applications requiring high linearity. Evaluate the I2C speed requirements against the system clock capabilities.

Digital To Analog Converters Part Context

This part belongs to the DAC757x family of low-power, 12-bit digital-to-analog converters. The family includes variants with different pin counts and resolutions, such as the DAC7571 (single channel) and DAC7572 (dual channel). The IDGS suffix denotes the industrial temperature range and TSSOP package style.

Digital To Analog Converters Replacement Considerations

The DAC7574IDGSR is a direct functional equivalent without the RoHS suffix. The DAC7574IDGST offers the same specifications in a smaller VQFN package. For lower channel counts, the DAC7572 series provides dual-channel options with similar performance characteristics.
