DAC7614UB/1K

Digital To Analog Converters Overview

The DAC7614UB/1K is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with buffered voltage outputs and a serial interface for data input. The device operates on a single 3V to 3.6V supply, consuming only 2.4mW of power. It provides a sampling rate of 89 kS/s and achieves a settling time of 10 µs. Key accuracy specifications include a gain error of 0.2% FSR and a reset-to-mid-scale feature. The component is housed in a 16-pin SOIC package and is supplied in a reel format.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels within a single compact package.
• Utilizes a low-power R-2R architecture optimized for battery-operated applications.
• Includes a hardware reset function that forces all outputs to mid-scale upon activation.

Digital To Analog Converters Applications

• Portable instrumentation systems requiring multi-channel signal generation
• Industrial process control loops with low channel count requirements
• Programmable voltage references for sensor biasing

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'UB/1K' against official datasheets to confirm the tape-and-reel packaging configuration. Ensure the operating environment remains within the specified -40°C to +85°C temperature range. Confirm that the 3V to 3.6V supply voltage aligns with the system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required with minimal power consumption. Compare against the DAC7614E variant if a 5V supply or SSOP-20 package is preferred. Evaluate the 89 kS/s update rate against application bandwidth needs. Consider the 0.2% FSR gain error tolerance relative to system accuracy requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7614 family of quad 12-bit converters. It shares architectural similarities with the DAC7615 and DAC7616 series but differs in supply voltage specifications and pinout configurations. The UB suffix typically denotes the SOIC-16 package variant designed for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

The DAC7614E/1K serves as a functional alternative offering identical electrical performance but utilizes a 5V supply and an SSOP-20 package. Verify pin compatibility and voltage level shifts when substituting between these variants.
