DAC7625U/1K

Digital To Analog Converters Overview

The DAC7625U/1K is a precision, quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture and delivers buffered voltage outputs. The device operates on a single 5V supply (4.75V to 5.25V) with a typical power consumption of 15 mW. It utilizes a parallel interface for data input and achieves a sampling rate of 100 kS/s with a settling time of 10 µs. The component is housed in a 28-pin SOIC 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 DAC channels with buffered voltage outputs in a single package.
• Employs an R-2R resistor string architecture to ensure low power consumption and high precision.
• Features a parallel digital interface compatible with standard microprocessor systems.
• Includes internal reset functionality to initialize outputs to mid-scale upon power-up.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing single-supply operation
• Battery-powered test equipment needing low power consumption

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the /1K designation typically indicates reel packaging. Ensure compatibility with the target system's voltage levels and interface timing requirements. Check for moisture sensitivity level (MSL 3) handling precautions during assembly. Confirm RoHS compliance status for environmental regulations. Validate that the SOIC-28 footprint matches the PCB design constraints.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution is required without external buffering circuitry. Compare against the DAC7624U/1K if mid-scale reset functionality is not needed. Consider the DAC7615 series if serial interface space savings are prioritized over parallel speed. Evaluate power dissipation limits relative to the thermal environment of the SOIC-28 package.

Digital To Analog Converters Part Context

This part belongs to the DAC7625 family of quad 12-bit DACs from Texas Instruments. It shares architectural similarities with the DAC7624 but adds specific reset features. The U suffix denotes the SOIC-28 surface-mount package variant. The /1K suffix specifies the tape-and-reel quantity for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7625UB serves as a tube-packaged alternative within the same functional family. Verify pinout compatibility before substituting with other quad DAC models from different manufacturers.
