DAC7551IDRNT

Digital To Analog Converters Overview

The DAC7551IDRNT is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. The device features a resistive string architecture with buffered voltage outputs and supports SPI and DSP serial 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

• Provides buffered voltage output capability for direct driving of downstream circuits without external amplification.
• Supports standard SPI and DSP compatible serial interfaces for flexible microcontroller integration.
• Ensures high linearity accuracy with specified integral and differential non-linearity values.

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 compact surface-mount packaging.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'NT' indicates tape and reel packaging when sourcing components. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the operating environment remains within the specified -40°C to +105°C junction temperature limits. Check for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with buffered outputs. It is suitable for designs constrained by the 12-USON footprint. Consider alternative models if differential outputs or higher sampling rates are necessary. Verify that the system interface matches the supported SPI/DSP protocols. Ensure power supply rails fall within the 2.7V to 5.5V operational range.

Digital To Analog Converters Part Context

This part belongs to the DAC7551 family of precision digital-to-analog converters. It shares core specifications with variants like the DAC7551IDR but differs in packaging configuration. The device complements Texas Instruments' portfolio of low-power data converters designed for space-constrained applications.

Digital To Analog Converters Replacement Considerations

The DAC7551IDRNTG4 is listed as a discontinued equivalent. Designers should transition to the DAC7551IDRNT for continued availability. Verify pin compatibility and electrical parameters remain identical during substitution.
