DAC7644EB

Digital To Analog Converters Overview

The DAC7644EB is a precision, quad 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with buffered voltage outputs and supports a parallel data interface. The device operates within a supply voltage range of 4.75 V to 5.25 V and achieves a sampling rate of 100 kS/s per channel. Key performance metrics include a settling time of 10 µs, a gain error of 0.08% FSR, and power consumption of 7.5 mW. It is housed in a 48-pin SSOP package and functions across a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit DAC channels with buffered voltage outputs for high-precision signal generation.
• Utilizes an R-2R resistor network architecture to ensure stable conversion characteristics.
• Includes a reset function that forces all outputs to mid-scale upon initialization or command activation.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog output.
• Programmable logic controller (PLC) modules for signal conditioning.
• Test and measurement equipment needing precise voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and moisture sensitivity level. Ensure compatibility with standard 5V logic levels for the parallel interface. Check RoHS compliance status and humidity sensitivity classification prior to procurement to meet storage and handling requirements.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel configuration with 16-bit resolution is required. The parallel interface necessitates sufficient GPIO availability on the host microcontroller. Consider the 10 µs settling time and 100 kS/s update rate against system bandwidth requirements. The 48-SSOP package limits pin count compared to larger footprints but offers surface-mount convenience.
