DAC7553IRGTTG4

Digital To Analog Converters Overview

The DAC7553IRGTTG4 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. Key performance metrics include a settling time of 5 µs, an integral nonlinearity (INL) of ±0.35 LSB, and a differential nonlinearity (DNL) of ±0.08 LSB. It utilizes standard serial interfaces including SPI and DSP modes. The component is housed in a 16-pin VQFN package and is rated for operation between -40°C and +105°C.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distribution channels as this specific suffix variant may be discontinued or superseded. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Cross-reference the full part number against current manufacturer lifecycle notices to ensure long-term availability for production runs.

Digital To Analog Converters Selection Notes

Select this component when dual-channel isolation is required within a compact footprint. Compare against the DAC7552 if only a single channel is needed to optimize cost. Ensure the system voltage range aligns with the 2.7 V to 5.5 V specification. Verify that the serial interface timing meets the microcontroller's clock speed capabilities.

Digital To Analog Converters Part Context

This part belongs to the DAC755x family of ultralow glitch voltage-output DACs. It shares architectural similarities with the DAC7552 but provides two independent channels instead of one. The 'G4' suffix indicates lead-free construction and environmental compliance according to Texas Instruments standards. It serves as a higher-density alternative to single-channel variants in space-constrained designs.

Digital To Analog Converters Replacement Considerations

The DAC7553IRGTT is listed as a manufacturer-recommended substitute. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in packaging or tape-and-reel specifications.
