DAC7614U

Digital To Analog Converters Overview

The DAC7614U is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and serial interface for data input. The device operates with analog supply voltages of 5 V and 5 V, and a digital supply voltage of 5 V. Key performance metrics include a settling time of 10 µs, a sampling rate of 89 kS/s, and power consumption of 15 mW. Differential nonlinearity is specified at +/- 1 LSB, while integral nonlinearity is +/- 2 LSB. Gain error is limited to 0.2% FSR. It is housed in a 20-pin SSOP package and supports operation within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit voltage output channels within a single compact package.
• Utilizes a serial interface compatible with standard DSP and microcontroller systems.
• Includes a reset function that returns outputs to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation with battery-powered constraints
• Data acquisition systems needing precise voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, such as tube or reel configurations. Ensure compatibility with the target board's thermal management requirements given the SSOP-20 footprint. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required without external multiplexing. Compare against the DAC7615U if a smaller SOIC-16 package is preferred for space-constrained designs. Evaluate the 10 µs settling time against application speed requirements to ensure adequate performance margins.

Digital To Analog Converters Part Context

This part belongs to the DAC7614 series, which provides low-power, 12-bit resolution solutions. It serves as a direct alternative to other quad-channel DACs in the market, offering a balance between precision and power efficiency for general-purpose analog output applications.

Digital To Analog Converters Replacement Considerations

The DAC7614E is a verified equivalent variant within the same series, differing primarily in packaging type rather than core electrical functionality.
