DAC7644EBG4

Digital To Analog Converters Overview

The DAC7644EBG4 is a quad, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features a parallel interface and R-2R architecture with buffered voltage outputs. The device operates on a single 5V digital supply and dual ±5V analog supplies, consuming 7.5 mW of power. Key electrical specifications include a settling time of 10 µs, a gain error of 0.08% FSR, and an operating temperature range from -40°C to +85°C. It is housed in a 48-pin SSOP package.

Digital To Analog Converters Feature Summary

• Provides four independent 16-bit precision voltage outputs
• Integrates internal reference reset capability to mid-scale
• Utilizes R-2R resistor ladder architecture for conversion

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Precision test and measurement equipment
• Automotive instrumentation modules

Digital To Analog Converters Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the 48-SSOP package dimensions match the target PCB footprint. Ensure the parallel data interface timing requirements align with the host controller capabilities before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 16-bit channels are required with low power consumption. The parallel interface suits applications where high throughput is needed without serial overhead. Consider the ±5V analog supply requirement during power budgeting. Verify that the 10 µs settling time meets the system's update rate constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC7644 family of quad digital-to-analog converters. It serves as a higher-resolution alternative to 12-bit or 14-bit variants within the same product line. The EB variant typically denotes a specific package and temperature grade configuration offered by Texas Instruments for industrial applications.

Digital To Analog Converters Replacement Considerations

The DAC7644EB is listed as an alias or predecessor. Check datasheets for pinout compatibility and electrical parameter differences between the standard EB and the G4 (lead-free) versions before substitution.
