DAC7715UBG4

Digital To Analog Converters Overview

The DAC7715UBG4 is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R architecture and features buffered voltage outputs with a settling time of 10µs. The device operates on dual analog and digital power supplies ranging from ±14.25V to ±15.75V. It supports SPI-compatible serial interfaces and includes a reset function to mid-scale. The component is housed in a 16-SOIC package and is rated for operation between -40°C and +85°C. Key accuracy metrics include maximum INL/DNL of ±1 LSB and gain error of 0.05% FSR.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 12-bit DACs within a single integrated circuit.
• Serial interface compatibility allowing simplified connection to microprocessors and DSP systems.
• Internal reset mechanism ensures outputs return to mid-scale upon initialization or fault conditions.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply architectures needing precise voltage references
• Data acquisition front-ends utilizing serial communication buses

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized channels as the DAC7715UBG4 is listed as obsolete. Confirm RoHS3 compliance status and check for valid replacement options such as the DAC7714UB due to manufacturing discontinuation. Ensure supply chain sources provide original manufacturer documentation to avoid counterfeit risks associated with end-of-life parts.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, high-voltage, serial-input DAC is required. Compare against the DAC7714UB for potential pin-compatible alternatives if availability is critical. Consider the specific ±15V supply requirement and SOIC-16 footprint constraints during PCB layout design. Verify that the 10µs settling time meets system bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7715 family of precision data converters. It shares architectural similarities with the DAC7714 and DAC7724 but differs in interface type and channel configuration. The 'UBG4' suffix indicates a specific tape-and-reel or tube packaging variant compliant with environmental standards. It serves as a legacy solution for industrial applications transitioning to newer generations.

Digital To Analog Converters Replacement Considerations

Public confirmed substitutes include DAC7714UB and DAC7715UB. Verify pinout compatibility and software register settings before substitution. The DAC7714UB offers parameter equivalence but may require firmware adjustments for channel mapping differences.
