LM2917N

Overview

The LM2917N 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 (INL) of +/- 1% FSR. It is housed in an 8-pin PDIP package with through-hole mounting style. The operational temperature range extends from -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between voltage signals and frequency pulses
• Operates reliably on a single power supply rail
• Provides accurate signal processing with specified integral nonlinearity

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm pinout and functional variations. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference the datasheet revision history for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Selection Notes

Select this component when a single-supply solution for frequency modulation or demodulation is required. Consider the 10 kHz full-scale frequency limit for application bandwidth constraints. Evaluate the PDIP-8 package suitability for through-hole assembly processes compared to surface-mount alternatives within the same product family.

Part Context

This device belongs to the LM2917 series of data converter ICs. It shares functional similarities with the LM2907 but offers distinct performance characteristics tailored for precision applications. The component is categorized under voltage-to-frequency and frequency-to-voltage converters within the broader analog signal processing portfolio.

Replacement Considerations

Consult the official datasheet for direct pin-compatible substitutes within the LM2917 family. Verify that alternative part numbers maintain identical electrical specifications and package dimensions to ensure seamless integration without circuit redesign.
