DAC7714UB

Digital To Analog Converters Overview

The DAC7714UB is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with serial data interface and voltage output. The device operates on dual analog power supplies of ±15 V and digital supply of ±15 V, within a temperature range of -40°C to +85°C. Key performance metrics include a settling time of 10 µs, sampling rate of 89 kS/s, and power consumption of 45 mW. Linearity specifications are ±1 LSB for both DNL and INL, with a gain error of 0.05% FSR. It is housed in a 16-pin SOIC package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 12-bit DAC outputs in a single package.
• Serial interface compatibility simplifies connection to microprocessors and digital control systems.
• Integrated reset function allows the output to return to mid-scale upon power-up or command.

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 buffered voltage outputs for sensor simulation.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix and manufacturer date code against current Texas Instruments documentation to ensure component authenticity and compliance with RoHS standards. Confirm that the SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required with 12-bit resolution and serial connectivity. Ensure the design supports ±15 V dual power supplies, as the device does not operate on single low-voltage rails. Consider the 10 µs settling time for bandwidth limitations in high-speed applications.

Digital To Analog Converters Part Context

The DAC7714UB belongs to the DAC7714 series of precision digital-to-analog converters. It serves as a multi-channel alternative to single-channel devices, reducing board space in applications requiring multiple simultaneous analog outputs. The series is characterized by its R-2R ladder structure and robust industrial operating temperature range.

Digital To Analog Converters Replacement Considerations

The DAC7715UB is documented as a parameter-equivalent substitute. Verify pinout compatibility and interface timing differences between the serial variants before implementation.
