LM331AN/NOPB

Overview

The LM331AN/NOPB is a precision voltage-to-frequency and frequency-to-voltage converter manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 40 V and supports frequencies from 1 Hz to 100 kHz. The device features a maximum linear error of 0.02% and utilizes an 8-pin PDIP package for through-hole mounting.

Feature Summary

• Provides bidirectional conversion between analog voltage signals and digital frequency outputs.
• Delivers high-precision performance with minimal linear error across the operating range.

Applications

• Precision analog-to-digital conversion systems
• Frequency modulation circuits
• Long-distance signal transmission interfaces

Procurement Notes

Verify the specific suffix 'AN/NOPB' against the manufacturer's current datasheet to confirm lead times and availability, as these attributes are subject to change. Ensure the procurement channel provides valid traceability documentation for this component variant.

Selection Notes

Select this component when a single-supply operation between 4 V and 40 V is required. It is suitable for applications demanding low linear error and wide dynamic range. Consider the 8-pin DIP package constraints for PCB layout and thermal management during integration.

Part Context

This part belongs to the LM331 family of voltage-to-frequency converters. It serves as a bridge between analog sensor data and digital processing systems, enabling accurate measurement and transmission of physical parameters in industrial and scientific instrumentation environments.

Replacement Considerations
