LM231AN/NOPB

Overview

The LM231AN/NOPB is a precision voltage-to-frequency converter manufactured by Texas Instruments. It operates within a wide frequency range of 1 Hz to 100 kHz full scale. The device is housed in an 8-PDIP package and supports a wide operating temperature range from -25°C to +85°C. It features ensured linearity with a maximum error of 0.01%. This component is designed for analog-to-digital conversion applications, offering improved performance in existing voltage-to-frequency conversion circuits while maintaining low cost and simplicity.

Feature Summary

Precision voltage-to-frequency conversion capability
Ensured linearity with maximum 0.01% error
Wide operating temperature range support

Applications

Analog-to-digital conversion circuits
Voltage-to-frequency conversion systems
Low-cost measurement instrumentation

Procurement Notes

Verify the specific suffix AN/NOPB against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the 8-PDIP package matches your PCB footprint requirements. Confirm the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when precise voltage-to-frequency conversion is required with tight linearity constraints. It is suitable for applications needing a wide dynamic frequency range up to 100 kHz. Consider the through-hole packaging if surface mount options are not feasible. Evaluate thermal management needs based on the specified operating temperature limits.

Part Context

This part belongs to the LM231/LM331 family of precision voltage-to-frequency converters. It serves as a bridge between analog signals and digital counting systems. The NOPB suffix indicates a lead-free and RoHS-compliant version of the original National Semiconductor design, now produced under Texas Instruments.

Replacement Considerations

The LM331AN/NOPB is a public confirmed substitute within the same family, offering similar functionality. Verify pin compatibility and electrical specifications against the target application requirements before substitution.
