DAC7553IRGTR

Digital To Analog Converters Overview

The DAC7553IRGTR is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device features a resistor-string architecture with buffered voltage outputs and supports serial interfaces including SPI, Microwire, QSPI, and DSP modes. Key performance metrics include a settling time of 5 µs, a sampling rate of 1 MS/s, and low power consumption of 675 µW. Nonlinearity specifications are defined by an INL of ±0.35 LSB and DNL of ±0.08 LSB. It is housed in a 16-VQFN package and functions across a temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration with independent 12-bit resolution for simultaneous signal generation.
• Integrated output buffers provide high drive capability while maintaining low glitch energy.
• Flexible serial interface compatibility allows connection to standard microcontrollers and DSPs.
• Ultra-low power operation ensures extended battery life in portable applications.

Digital To Analog Converters Applications

• Portable medical instrumentation requiring precise multi-channel signal control
• Industrial process control systems utilizing isolated sensor feedback loops
• Battery-powered test and measurement equipment demanding low power consumption

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the operating environment remains within the specified -40°C to +105°C thermal limits to maintain guaranteed performance parameters.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required alongside minimal power usage. Compare against single-channel variants if only one output is necessary to optimize board space. Consider the 16-VQFN package constraints during PCB layout planning to ensure adequate thermal dissipation and soldering reliability for surface-mount assembly processes.

Digital To Analog Converters Part Context

This part belongs to the DAC755x family of ultralow glitch digital-to-analog converters. It shares architectural similarities with the DAC7552 and DAC7554 but differs in channel count. The IRGTR designation specifies the industrial temperature grade and reel packaging format, distinguishing it from other package options like the RGTT cut tape variant.

Digital To Analog Converters Replacement Considerations

The DAC7553IRGTT serves as a direct functional substitute differing primarily in packaging format (cut tape versus reel). Verify pinout compatibility and electrical specifications before interchange. No alternative manufacturers offer identical pin-compatible replacements within this specific performance tier.
