DAC7624U/1KG4

Digital To Analog Converters Overview

The DAC7624U/1KG4 is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture with buffered voltage outputs and a parallel interface. The device operates on a single 5V supply, consuming 15 mW of power. Key electrical specifications include a settling time of 10 µs, a gain error of 0.2% FSR, and integral nonlinearity (INL) of ±2 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Utilizes an R-2R resistor string structure to ensure stable performance across the operating temperature range.
• Includes a reset function that forces all output channels to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Data acquisition systems utilizing parallel microcontroller interfaces

Digital To Analog Converters Procurement Notes

Verify the suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the '/1K' designation corresponds to the reel packaging format containing 1000 units. Ensure the SOIC-28 footprint matches the target PCB layout constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a parallel interface is required for high-speed updates without serial protocol overhead. The 12-bit resolution and 10 µs settling time suit applications needing moderate precision. Verify that the 5V single-supply operation aligns with the system's power distribution network and that the buffered outputs meet the load requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7624 family of quad-channel converters. It shares architectural similarities with the DAC7625 but differs in specific linearity specifications. The U suffix denotes the SOIC-28 surface-mount package, while the /1K variant specifies the tape-and-reel quantity for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7625U/1K serves as a functional substitute within the same series. Both devices share identical pinouts, package types, and core specifications. Designers should verify that the specific INL and DNL tolerances of the replacement part meet the application's accuracy requirements.
