LM2907N-8/NOPB

Overview

The LM2907N-8/NOPB is a frequency-to-voltage and voltage-to-frequency converter manufactured by Texas Instruments. It operates on a single power supply ranging from 6 V to 28 V. The device supports a full-scale frequency of 10 kHz with an integral nonlinearity of +/- 1% FSR. It is housed in an 8-pin PDIP package designed for through-hole mounting. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between frequency and voltage signals
• Operates reliably on a single power supply rail
• Provides stable performance across industrial temperature ranges

Applications

• Tachometer circuits
• Speed switch building blocks
• Frequency measurement systems

Procurement Notes

Verify the specific suffix N-8 against the manufacturer datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the PDIP-8 through-hole package aligns with the PCB footprint. Confirm RoHS compliance status via the official documentation before finalizing procurement decisions.

Selection Notes

Select this component when a single-supply operation is required for frequency-to-voltage applications. The 10 kHz full-scale frequency and +/- 1% FSR linearity suit moderate precision tasks. Consider the PDIP-8 package constraints if surface-mount alternatives like the MX variant are not feasible for the assembly process.

Part Context

This part belongs to the LM2907 series of data converters. It serves as a dedicated solution for analog signal processing where frequency inputs must be translated into proportional voltage levels or vice versa. The NOPB designation indicates lead-free construction compliant with environmental standards.

Replacement Considerations

LM2907MX-8/NOPB offers the same functionality in an SOIC-8 surface-mount package.
