DAC7611UB

Digital To Analog Converters Overview

The DAC7611UB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single +5V supply and features an R-2R resistor ladder architecture with buffered voltage outputs. The device includes an internal 2.435V reference and accepts serial data via a 3-wire interface compatible with standard DSPs and microcontrollers. Key electrical specifications include a settling time of 10 microseconds to 1 LSB for full-scale steps, a maximum sampling rate of 89 kS/s, and a typical power consumption of 2.4 mW. It is housed in an 8-pin SOIC package and is specified for operation over the industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output amplifier providing rail-to-rail swing capability
• Internal precision reference eliminates external component requirements
• Synchronous 3-wire serial interface ensures compatibility with common digital controllers

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Battery-powered instrumentation benefiting from low power consumption
• Programmable gain amplifiers and variable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'UB' against the manufacturer's current datasheet to confirm package type and tape-and-reel configuration. Ensure the order matches the required industrial temperature grade and RoHS compliance status as defined in the official documentation before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. It is suitable for designs constrained by space due to its compact SOIC-8 footprint. Verify that the system clock speed supports the required 89 kS/s update rate and that the 3-wire interface aligns with the host processor's available communication ports.

Digital To Analog Converters Part Context

This part belongs to the DAC761x family of low-power, serial input DACs. It shares architectural similarities with the DAC7612 (dual channel) and DAC7616 (quad channel), offering consistent performance characteristics across the series while varying in channel count and pinout configuration.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the DAC7612U for dual-channel applications and the DAC7616UB for quad-channel requirements. Cross-family replacements may require interface adaptation if the target device utilizes different serial protocols or voltage levels.
