LM2917N-8

Overview

The LM2917N-8 is a monolithic integrated circuit manufactured by Texas Instruments, functioning as both a voltage-to-frequency and frequency-to-voltage converter. It operates on a single power supply ranging from 6 V to 28 V. The device features a full-scale frequency capability of 10 kHz and maintains an integral nonlinearity (INL) of +/- 1% FSR. Designed for through-hole mounting, it is housed in an 8-pin PDIP package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between voltage signals and frequency pulses
• Operates reliably on a single power supply source
• Provides stable linear performance across the specified frequency range

Applications

• Tachometer circuits for rotational speed measurement
• Speed switch building blocks
• Frequency modulation demodulation systems

Procurement Notes

Verify the specific suffix 'N-8' against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure the procurement channel provides original Texas Instruments components with valid traceability documentation. Confirm RoHS compliance status matches project requirements before finalizing orders.

Selection Notes

Select this component when a single-supply solution for frequency-to-voltage conversion is required. The PDIP-8 package suits prototyping and applications where surface mount technology is not mandated. Consider the 10 kHz bandwidth limit and +/- 1% INL specification against system accuracy needs.

Part Context

This part belongs to the LM2917 series, which includes variants like the LM2917N/NOPB and LM2917MX-8/NOPB. These devices share core functional architectures but differ in packaging styles such as SOIC or PDIP. The series is widely recognized for industrial tachometer and speed control applications.
