DAC7614UBG4

Digital To Analog Converters Overview

The DAC7614UBG4 is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features four buffered voltage outputs and utilizes an R-2R resistor ladder architecture. The device operates with a single analog supply voltage ranging from 3 V to 5.25 V and a digital supply voltage between 2.7 V and 5.5 V. It supports serial data interfaces including SPI, Microwire, and DSP formats. Key performance metrics include a settling time of 10 µs, a sample rate of 89 kS/s, and an integral nonlinearity (INL) of ±2 LSB. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Supports standard serial communication protocols including SPI, Microwire, and DSP interfaces.
• Utilizes an R-2R resistor ladder architecture to ensure stable conversion performance.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply designs needing precise voltage references
• Data acquisition systems utilizing external digital-to-analog conversion

Digital To Analog Converters Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status according to Texas Instruments documentation. Confirm the package type matches the required PCB footprint, as the U variant denotes a SOIC-16 package. Ensure the ordering part number aligns with the desired tape-and-reel or tube packaging configuration for manufacturing integration.

Digital To Analog Converters Selection Notes

Select this component when a design requires four isolated voltage outputs with 12-bit resolution. It is suitable for applications where low power consumption and serial interface compatibility are priorities. Consider the 10 µs settling time and 89 kS/s update rate against system bandwidth requirements before finalizing the design.

Digital To Analog Converters Part Context

This device belongs to the DAC761x family of precision digital-to-analog converters. It shares architectural similarities with the DAC7615 and DAC7616 but differs in supply voltage specifications and channel configurations. The UBG4 designation identifies the specific package style and environmental compliance attributes within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC7615U serves as a functional equivalent within the same series. Verify pinout compatibility and supply voltage ranges when substituting. The DAC7616 offers similar performance but may require different power management considerations due to its specific operating characteristics.
