DAC7552IRGTTG4

Digital To Analog Converters Overview

The DAC7552IRGTTG4 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs and supports sampling rates up to 1 MS/s. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It utilizes standard serial interfaces including SPI, Microwire, QSPI, DSP, and 3-wire modes. Key performance metrics include a settling time of 5 µs, a gain error of 0.15% FSR, and power consumption of 675 µW. The component is housed in a 16-VQFN package (3x3 mm) and functions within an industrial temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration with independent 12-bit resolution per channel
• Low glitch energy output suitable for precision applications
• Flexible serial interface compatibility with multiple protocol standards
• Ultra-low power consumption optimized for battery-operated systems

Digital To Analog Converters Applications

• Portable instrumentation requiring low power and high accuracy
• Industrial process control systems with multi-channel signal generation
• Battery-powered measurement devices needing extended operational life
• Programmable voltage references in compact embedded designs

Digital To Analog Converters Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and manufacturing origin details against current Texas Instruments documentation. Confirm availability status as distributors may list obsolete or end-of-life variants differently. Ensure the VQFN-16 package dimensions match PCB footprint requirements precisely. Check for moisture sensitivity level (MSL 3) handling constraints during assembly processes to prevent package damage.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 12-bit resolution is required alongside ultra-low power constraints. Compare against the DAC7553 if additional features like SDO are necessary. Verify that the 5 µs settling time meets system speed requirements. Ensure the 2.7 V minimum supply voltage aligns with the available power rails in the target design environment.

Digital To Analog Converters Part Context

This part belongs to the DAC7552 family of microPOWER digital-to-analog converters. It shares architectural similarities with the DAC7551 (single channel) and DAC7553 (dual channel with enhanced features). The IRGTTG4 designation specifies the industrial temperature range, reel packaging, and lead-free/RoHS compliant construction typical of modern Texas Instruments surface-mount components.

Digital To Analog Converters Replacement Considerations

DAC7552IRGTT is the non-RoHS predecessor variant recommended by the manufacturer. For single-channel applications, consider the DAC7551 series. If higher resolution or different packaging is needed, evaluate the DAC8552 family.
