DAC7644EG4

Digital To Analog Converters Overview

The DAC7644EG4 is a quad-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with buffered voltage outputs. The device operates on a single 5V digital supply and dual ±5V analog supplies. It supports parallel word input interfaces and includes a reset function to mid-scale. Key performance metrics include a settling time of 10 microseconds, integral nonlinearity (INL) of ±3 LSB, and differential nonlinearity (DNL) of ±2 LSB. Power consumption is specified at 7.5 mW. The component is housed in a 48-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 16-bit voltage outputs
• Integrated output buffers for direct drive capability
• Parallel data interface compatible with standard microprocessors
• Power-on reset circuit ensures outputs initialize to mid-scale

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel precision
• Programmable gain amplifier circuits
• Multi-axis motion control applications
• Data acquisition system front-ends

Digital To Analog Converters Procurement Notes

Verify the presence of the G4 suffix to confirm lead-free compliance and RoHS adherence. Confirm the package designation matches the required 48-SSOP form factor. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range. Validate that the system power rails align with the required ±5V analog and 5V digital supplies.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 16-bit channels are necessary. The R-2R architecture offers fast settling times suitable for dynamic applications. Consider the parallel interface requirements against available microprocessor pins. Evaluate the need for internal buffering versus external amplification based on load impedance.

Digital To Analog Converters Part Context

This part belongs to the DAC7644 family of precision digital-to-analog converters. The EG4 suffix indicates a specific tape-and-reel or tube packaging variant compliant with environmental standards. It serves as a high-resolution alternative to lower-bit counterparts in the same series.

Digital To Analog Converters Replacement Considerations

The DAC7644E is the non-compliant predecessor. Verify if the G4 suffix implies identical electrical characteristics. Check for pin-compatible alternatives within the DAC76xx series if supply constraints change.
