DAC7611U/2K5G4

Digital To Analog Converters Overview

The DAC7611U/2K5G4 is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture to provide voltage output with a settling time of 7 microseconds. The device operates on a single 5 V supply for both analog and digital domains, supporting a sampling rate of 132 kS/s. It features a 3-wire serial interface compatible with standard SPI protocols. Key linearity specifications include differential nonlinearity and integral nonlinearity of ±0.5 LSB. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates a precision R-2R ladder network for stable voltage conversion without requiring external components.
• Supports high-speed serial communication through a simple three-wire interface compatible with microcontrollers.
• Delivers accurate signal generation with guaranteed linearity performance across the full operating temperature range.

Digital To Analog Converters Applications

• Programmable voltage sources and reference circuits
• Industrial process control signal generation
• Battery-powered instrumentation systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance when sourcing. Confirm the /2K5 designation corresponds to tape-and-reel packaging rather than tube quantities. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Digital To Analog Converters Selection Notes

Select this component for designs requiring a single-channel output with moderate resolution and speed. Compare against the DAC7612 if dual-channel capability is needed. Verify that the 5 V supply requirement aligns with the system power budget and that the SOIC-8 package fits the available board space constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC7611 family of precision digital-to-analog converters. The U suffix denotes the SOIC-8 surface-mount package variant. The G4 suffix typically signifies lead-free manufacturing compliance. The /2K5 suffix indicates a specific reel quantity packaging option distinct from standard tube packaging.

Digital To Analog Converters Replacement Considerations

The DAC7612U/2K5G4 serves as a direct functional substitute offering dual-channel capability within the same package footprint. Designers requiring higher resolution or different interface types must evaluate alternative architectures beyond this specific series.
