DAC7624UB/1K

Digital To Analog Converters Overview

The DAC7624UB/1K is a precision, quad-channel digital-to-analog converter manufactured by Texas Instruments. It features a 12-bit resolution and an R-2R architecture, delivering buffered voltage outputs with a settling time of 10 µs. The device operates on a single 5V digital supply (4.75V to 5.25V) and supports parallel data interfaces. Designed for surface-mount installation in SOIC-28 packages, it functions within a temperature range of -40°C to +85°C. Key performance metrics include a gain error of 0.2% FSR and low power consumption of 15 mW.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with buffered voltage outputs for simultaneous signal generation.
• Utilizes R-2R resistor ladder architecture to ensure stable conversion accuracy and linearity.
• Supports standard parallel digital interfaces for straightforward integration into microcontroller systems.
• Includes internal reset functionality to initialize outputs to mid-scale upon power-up or command.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog signal generation.
• Programmable logic controller (PLC) output modules for actuator control.
• Data acquisition systems needing precise analog reference voltages.
• Test and measurement equipment requiring stable, multi-channel voltage sources.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '/1K' confirms the reel packaging quantity of 1000 units as documented in distributor specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements against your assembly line capabilities. Ensure the SOIC-28 footprint matches your PCB design guidelines before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel configuration is required alongside 12-bit resolution and parallel interface compatibility. Compare against the DAC7625 if higher absolute accuracy is needed, noting the DAC7624 has a 0.2% FSR gain error versus 0.05% for the DAC7724. Verify that the 5V single-supply operation aligns with your system's power distribution network constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC7624/DAC7625 family of precision quad DACs from Texas Instruments. It shares the same physical package and basic interface structure as the DAC7625 but differs in accuracy specifications. The series is designed for general-purpose industrial applications where moderate precision and multi-channel capability are prioritized over ultra-high accuracy.

Digital To Analog Converters Replacement Considerations

The DAC7625UB serves as a direct pin-compatible alternative with improved gain error specifications. For unbuffered output requirements, consider the DAC7624U variant. Verify that any substitute maintains the SOIC-28 package and 12-bit resolution to ensure mechanical and functional compatibility.
