DAC7553IRGTT

Digital To Analog Converters Overview

The DAC7553IRGTT is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an ultralow glitch impulse output and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a resistor-string architecture and provides buffered voltage outputs with a settling time of 5 µs. It supports multiple serial interface protocols including SPI, Microwire, DSP, QSPI, and 3-Wire. Packaged in a 16-pin VQFN (3x3 mm) format, it functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration with independent 12-bit resolution per channel
• Ultralow glitch impulse output capability for signal integrity
• Flexible serial interface compatibility with standard communication protocols
• Low power consumption suitable for battery-operated applications

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure that the component meets RoHS compliance requirements for your target market. Cross-reference the part number with official distributor catalogs to validate availability status and lead times before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required without external buffering. Compare the 12-bit resolution and 1 MS/s update rate against system bandwidth needs. Consider the VQFN-16 footprint constraints during PCB layout. Verify that the operating voltage range aligns with the system's power supply rails.

Digital To Analog Converters Part Context

This part belongs to the DAC755x family of low-power, 12-bit digital-to-analog converters. It shares architectural similarities with the DAC7552 but offers dual-channel functionality compared to single-channel variants. The IRGTT suffix indicates a specific thermal and packaging variant within the broader DAC7553 product line designed for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

The DAC7552IRGTT is a documented alternative within the same family, offering similar electrical characteristics. Verify pinout compatibility and software register mapping before substitution. Ensure that the replacement part meets the same environmental and packaging requirements.
