DAC7714UBG4

Digital To Analog Converters Overview

The DAC7714UBG4 is a quad 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with buffered voltage outputs and supports SPI serial interfaces. The device operates within a supply voltage range of ±14.25V to ±15.75V for both analog and digital domains. Key performance metrics include a settling time of 10µs, integral nonlinearity (INL) and differential nonlinearity (DNL) of ±1 LSB maximum, and a gain error of 0.05% FSR. It functions in temperatures from -40°C to +85°C and is housed in a 16-SOIC package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with buffered voltage outputs for simultaneous signal generation.
• Utilizes an R-2R resistor ladder architecture to achieve high precision with low integral and differential nonlinearity errors.
• Supports standard SPI serial communication interface for simplified microcontroller connectivity and control.
• Includes a reset function that forces all output channels to mid-scale upon initialization or command activation.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog signal generation.
• Data acquisition systems needing precise voltage reference distribution.
• Automotive instrumentation panels utilizing robust wide-temperature operation capabilities.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS3 compliance and moisture sensitivity level 3 handling requirements during storage and assembly. Check for parameter-equivalent alternatives such as the DAC7714UB if original stock is unavailable. Ensure packaging specifications match design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when designing systems requiring four synchronized 12-bit voltage outputs with high accuracy. The ±15V supply requirement suits applications with dual-rail power availability. Consider the 16-SOIC package dimensions for PCB layout compatibility. Evaluate the 10µs settling time against system bandwidth requirements to ensure adequate response speed for dynamic signals.

Digital To Analog Converters Part Context

This part belongs to the DAC771x family of precision quad DACs from Texas Instruments. It shares architectural similarities with the DAC7715 but differs in specific pinout or feature configurations. The 'G4' suffix indicates lead-free construction and environmental compliance. It serves as a specialized solution for multi-channel analog output needs in industrial environments.

Digital To Analog Converters Replacement Considerations

Public confirmed substitutes include the DAC7714UB. Verify pin compatibility and electrical parameters before substitution. The DAC7715UB is listed as a parameter equivalent but may require schematic review. Consult official datasheets for functional differences between these variants.
