DAC712U

Digital To Analog Converters Overview

The DAC712U is a 16-bit resolution, single-channel digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture and features a parallel digital interface for data input. The device provides a buffered voltage output with bipolar polarity and includes an internal voltage reference. Designed for through-hole mounting, it is housed in a 28-pin PDIP package measuring 35.69 x 6.73 x 4.57mm. Key performance specifications include a conversion rate of 100ksps, a maximum settling time of 6µs, and an overall non-linearity error of ±8LSB. The full-scale error is specified at ±0.2%FSR. It operates on dual power supplies within the range of ±11.4V to 16.5V and supports an industrial temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates an internal voltage reference to simplify circuit design and reduce external component count.
• Provides a buffered voltage output stage capable of driving loads directly without additional amplification.
• Features a parallel interface compatible with standard microcontrollers and DSP systems for high-speed data transfer.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Programmable gain amplifier circuits needing accurate reference voltage adjustments.
• Waveform generation equipment utilizing high-resolution digital inputs.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation when ordering, as packaging and temperature ranges may vary between PDIP and SOIC variants. Confirm that the required operating voltage aligns with the dual supply specification. Check current production status, as older revisions may be discontinued or subject to last-time buy notices. Ensure compatibility with the host system's parallel interface timing requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution is mandatory for low-noise applications. The parallel interface is suitable for systems with sufficient GPIO lines available. Consider the PDIP package only if through-hole assembly is required; otherwise, evaluate the SOIC variant for surface mount needs. Verify that the dual supply availability matches the existing power infrastructure of the target application.

Digital To Analog Converters Part Context

The DAC712U belongs to the DAC712 family of 16-bit precision digital-to-analog converters. This series is designed for applications demanding high accuracy and stability. The U suffix typically denotes the SOIC package version, while P indicates the PDIP package. Both variants share identical electrical characteristics but differ in physical footprint and mounting method. The family is known for its robust R-2R ladder structure ensuring monotonicity.

Digital To Analog Converters Replacement Considerations

The DAC712UK is listed as a recommended replacement by the manufacturer. Verify pinout compatibility and package dimensions before substitution. Ensure that any alternative part meets the same 16-bit resolution and parallel interface requirements.
