DAC5681IRGC25

Digital To Analog Converters Overview

The DAC5681IRGC25 is a discontinued 16-bit digital-to-analog converter manufactured by Texas Instruments. It features a single current-sink architecture housed in a 64-VQFN (9x9 mm) package with an exposed pad. The device operates on analog supply voltages between 3V and 3.6V, and digital supply voltages ranging from 1.71V to 2.15V. Key performance metrics include a typical settling time of 10.4ns, integral nonlinearity (INL) of ±4 LSB, and differential nonlinearity (DNL) of ±2 LSB. It supports LVDS parallel data interfaces and functions within a temperature range of -40°C to 85°C.

Digital To Analog Converters Feature Summary

• Integrates a high-speed 16-bit current-sink DAC core for precise signal generation.
• Supports LVDS parallel input interface for high-speed digital data transmission.
• Provides differential current outputs suitable for direct connection to external buffer amplifiers.

Digital To Analog Converters Applications

• Test and measurement equipment requiring high-resolution signal synthesis
• Wireless infrastructure base stations utilizing digital upconversion
• Medical imaging systems demanding precise analog waveform generation

Digital To Analog Converters Procurement Notes

This component has reached end-of-life status and is no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than authorized manufacturer channels. Buyers must confirm the authenticity of the source and inspect the physical condition of the units, as lead times and stock levels are unpredictable for obsolete parts. Compliance with RoHS3 standards remains documented in official records.

Digital To Analog Converters Selection Notes

Designers replacing this part should consider the DAC5681ZIRGCR, which offers similar specifications but includes interpolation capabilities. The selection process must account for the pinout compatibility between the standard DAC5681 and the Z-series variants. Engineers should verify that the target application can accommodate any differences in power consumption or interface requirements introduced by newer generations of the product family.

Digital To Analog Converters Part Context

The DAC5681 belongs to Texas Instruments' professional data converter portfolio, designed for demanding industrial and communications applications. This specific suffix indicates a 25-unit tray packaging configuration, distinct from the reel-based DAC5681ZIRGCR. The device represents a legacy solution for high-speed conversion tasks before the introduction of integrated interpolation filters in subsequent model iterations.

Digital To Analog Converters Replacement Considerations

The DAC5681ZIRGCR is listed as a similar replacement. Designers must evaluate functional differences, particularly regarding interpolation features, before substituting the obsolete part.
