DAC7551IDRNR

Digital To Analog Converters Overview

The DAC7551IDRNR is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a supply voltage range of 2.7V to 5.5V for both analog and digital domains. The device features a resistor string architecture with buffered voltage outputs and supports SPI and DSP interfaces. Key performance metrics include a settling time of 5µs, an INL of ±0.35 LSB, and a DNL of ±0.08 LSB. It is housed in a 12-USON (3x2) package with exposed pad and functions within a temperature range of -40°C to 105°C.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output stage eliminates the need for external operational amplifiers.
• Serial interface compatibility with standard SPI and DSP protocols simplifies system integration.
• Ultralow glitch impulse specification ensures clean transitions during code changes.

Digital To Analog Converters Applications

• Portable instrumentation requiring low power consumption
• Battery-powered data acquisition systems
• Process control loop actuators

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'NR' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact package variant and temperature grade required for the design. Cross-reference manufacturer documentation for any recent product change notices affecting assembly sites or materials.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is sufficient for the application. The 5µs settling time suits moderate-speed applications. Verify that the 12-USON footprint fits the PCB layout constraints. Consider the 2.7V minimum supply voltage if operating from lower voltage sources.

Digital To Analog Converters Part Context

This part belongs to the DAC7551 family of ultralow glitch, 12-bit voltage-output digital-to-analog converters. The family includes variants with different packaging options such as VSSOP and USON. The DAC7551 series is designed for applications requiring high accuracy and low power consumption in compact form factors.

Digital To Analog Converters Replacement Considerations

The DAC7551IDRNTG4 is listed as a discontinued alternative with the DAC7551IDRNT recommended as the manufacturer replacement. Verify pinout and electrical parameter compatibility before substitution.
