LM2917N-8/NOPB

Overview

The LM2917N-8/NOPB is a monolithic integrated circuit manufactured by Texas Instruments, designed for voltage-to-frequency and frequency-to-voltage conversion. It operates on a single power supply ranging from 6 V to 28 V. The device features a full-scale frequency of 10 kHz and an integral nonlinearity of +/- 1% FSR. It is housed in an 8-pin PDIP package suitable for through-hole mounting. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between voltage and frequency signals
• Operates with a single power supply configuration
• Provides high linearity performance for precision applications

Applications

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

Procurement Notes

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

Selection Notes

Select this component when a single-supply solution for frequency-to-voltage or voltage-to-frequency conversion is required. Consider the 10 kHz full-scale frequency limit and +/- 1% INL specification against system accuracy needs. Verify that the 6 V to 28 V operating voltage range fits the available power rails and that the through-hole package is compatible with the assembly process.

Part Context

This part belongs to the LM2917 series of voltage/frequency converters. It shares functional similarities with the LM2907 but offers distinct performance characteristics tailored for industrial control and measurement applications. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing standards.

Replacement Considerations

Consult the LM2907 datasheet for potential functional substitution if pin compatibility and electrical parameters allow. Verify that any alternative component meets the same single-supply operation and frequency conversion requirements.
