DAC7625U/1KG4

Digital To Analog Converters Overview

The DAC7625U/1KG4 is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage outputs with a settling time of 10 µs and a sampling rate of 100 kS/s per channel. The device operates on a single 5 V digital supply and dual ±5 V analog supplies, supporting both bipolar and unipolar output polarities. Key accuracy specifications include a differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±2 LSB. It is housed in a 28-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Features a reset function that returns all outputs to mid-scale upon power-up or command activation.
• Supports flexible output configurations allowing for either bipolar or unipolar voltage ranges via external reference selection.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation.
• Programmable power supply architectures needing precise voltage regulation.
• Test and measurement equipment utilizing high-resolution waveform synthesis.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free material standards. Ensure the ordering part number matches the exact package variant and temperature grade required for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when a parallel interface is preferred over serial protocols for simplified microcontroller integration. Consider the 10 µs settling time and 100 kS/s update rate to ensure compatibility with system bandwidth requirements. Verify that the available board space accommodates the 28-SOIC footprint and that the ±5 V analog supply rails are accessible.

Digital To Analog Converters Part Context

This part belongs to the DAC7624/DAC7625 family of quad-channel converters. The DAC7624 variant typically offers higher precision with lower noise characteristics, whereas the DAC7625 provides a cost-effective solution with standard accuracy metrics. Both share identical pinouts and functional interfaces, facilitating design flexibility across product lines.

Digital To Analog Converters Replacement Considerations

The DAC7624U/1KG4 serves as a higher-precision alternative within the same package and interface configuration. Designers may also evaluate the DAC7625UB variant if tape-and-reel packaging is required instead of tube packaging, provided the electrical parameters remain sufficient for the application.
