DAC712UB

Digital To Analog Converters Overview

The DAC712UB is a precision, single-channel 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture and features a parallel data interface for high-speed operation. The device operates on a dual power supply ranging from ±11.4V to ±16.5V and delivers a buffered voltage output. Key performance metrics include a settling time of 10µs, maximum integral nonlinearity (INL) of ±2 LSB, and maximum differential nonlinearity (DNL) of ±2 LSB. It is housed in a 28-pin SOIC package and is specified for operation within the commercial temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output stage eliminates the need for external amplifiers.
• Parallel interface design supports high-throughput data transfer requirements.
• Built-in reference architecture simplifies system design and component count.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Programmable power supplies with high resolution requirements
• Test and measurement equipment needing stable analog references

Digital To Analog Converters Procurement Notes

Verify current production status as the DAC712UK variant is listed as obsolete. Confirm availability of active replacement parts such as the DAC8734 series if long-term supply is required. Check specific ordering suffixes for packaging variations and ensure compliance with RoHS standards before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a single channel with 16-bit resolution and parallel interface is necessary. Ensure the system can accommodate the ±11.4V to ±16.5V dual supply requirement. Consider the 28-SOIC package dimensions for PCB layout constraints and verify that the 10µs settling time meets the application's speed specifications.

Digital To Analog Converters Part Context

The DAC712 belongs to the legacy DAC71x family of high-resolution converters. It serves as a foundational component for applications transitioning from lower resolution devices to 16-bit precision. The part is often compared with the DAC714 and DAC716 variants which offer different channel counts or interface options within the same architectural lineage.

Digital To Analog Converters Replacement Considerations

The DAC8734SRHAR is a recommended replacement. Verify pin compatibility and software register mapping differences between the parallel interface of the DAC712 and the serial interface of the DAC8734.
