DAC7552IRGTRG4

Digital To Analog Converters Overview

The DAC7552IRGTRG4 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an ultralow glitch impulse specification and voltage output buffers. The device operates on a single analog and digital power supply ranging from 2.7 V to 5.5 V. It supports serial interfaces including SPI, Microwire, and QSPI. The component is housed in a 16-pin VQFN package with a 3x3 mm footprint. Key electrical parameters include a settling time of 5 µs, a gain error of 0.15% FSR, and a typical power consumption of 675 µW at 5 V.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 12-bit DAC outputs within a compact surface-mount package.
• Ultralow glitch impulse design minimizes transient spikes during code transitions for signal integrity.
• Integrated voltage output buffers allow direct driving of loads without external amplification.
• Flexible serial interface compatibility with standard DSP and microcontroller communication protocols.

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring low power consumption
• Industrial process control loops utilizing single-supply operation
• Portable medical devices needing high accuracy in small form factors

Digital To Analog Converters Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments standards. Confirm the IRGTR designation corresponds to the tape-and-reel packaging format suitable for automated surface-mount assembly processes. Ensure the operating temperature range meets the -40°C to +105°C requirements for industrial environments.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance is required alongside strict glitch impulse limitations. Compare against the DAC7553 if additional serial data out (SDO) functionality is necessary for daisy-chaining applications. Consider the DAC7551 for single-channel designs or the DAC7554 for quad-channel configurations within the same family.

Digital To Analog Converters Part Context

This part belongs to the DAC755x series of 12-bit voltage-output digital-to-analog converters. It shares architectural similarities with the DAC7551, DAC7553, and DAC7554, differing primarily in channel count and specific interface features. The device utilizes a resistor-string architecture to achieve its specified resolution and linearity characteristics.

Digital To Analog Converters Replacement Considerations

The DAC7552IRGTT is a pin-compatible alternative offered by Texas Instruments. Verify that the tape-and-reel versus cut-tape packaging differences do not impact existing assembly equipment capabilities before substitution.
