2C444

Overview

The 2C444 is a Voltage-to-Frequency (V/F) converter manufactured by Burr-Brown, now part of Texas Instruments. It functions as an analog signal processing component designed to convert input voltage levels into proportional frequency outputs. This device facilitates the transmission of analog signals over long distances with high noise immunity and simplifies interfacing with digital systems such as microcontrollers and counters.

Feature Summary

• Provides accurate conversion of analog voltage inputs to digital frequency outputs
• Enables robust signal transmission in noisy environments through frequency modulation
• Simplifies interface requirements for downstream digital processing units

Applications

• Industrial process control systems requiring remote sensor data acquisition
• Data acquisition systems utilizing analog-to-digital conversion via frequency counting
• Test and measurement equipment needing precise voltage monitoring

Procurement Notes

Verify the specific suffix code on the component marking, as Burr-Brown parts often include letter codes indicating temperature range or packaging variations. Confirm that the source document explicitly lists the 2C444 variant as active or discontinued, as availability may be limited due to age. Cross-reference the manufacturer's official discontinuation notices to ensure compliance with current supply chain standards before procurement.

Selection Notes

Select this component when a linear voltage-to-frequency conversion is required for noise-immune signal transmission. Ensure the input voltage range matches the application's signal amplitude. Consider the output frequency linearity and accuracy specifications if high precision is needed. Verify compatibility with the receiving digital logic family regarding voltage levels and timing requirements.

Part Context

Burr-Brown was acquired by Texas Instruments in 2000. The 2C444 belongs to the legacy Burr-Brown portfolio of precision analog components. These parts are widely recognized for their performance in industrial applications. The product line has been integrated into TI's broader offering, maintaining the original design specifications while updating manufacturing processes where applicable.

Replacement Considerations

Publicly confirmed substitute part numbers for the 2C444 are not available in the provided documentation. Users should consult Texas Instruments' official replacement guides or contact technical support directly for qualified alternatives, as generic V/F converters may not match the specific performance characteristics of this Burr-Brown component.
