LM2917N/NOPB

Overview

The LM2917N/NOPB is a monolithic integrated circuit 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 capability of 10 kHz with an integral nonlinearity of +/- 1% FSR. It is housed in a PDIP-14 through-hole package and functions within a temperature range of -40°C to +85°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the required package style and temperature grade. Cross-reference datasheet revisions to validate current manufacturing status and any potential design changes affecting integration.

Selection Notes

Select this component when a single-supply solution for frequency conversion is required. Consider the PDIP-14 package for through-hole assembly needs. Evaluate the +/- 1% FSR nonlinearity against system accuracy requirements. Confirm that the 10 kHz full-scale frequency meets the input signal bandwidth constraints of the target application.

Part Context

This device belongs to the LM2917 series, which includes variants like the LM2917MX-8/NOPB in surface-mount packages. The N/NOPB designation specifically indicates the lead-free PDIP-14 through-hole configuration manufactured by Texas Instruments. It serves as a dedicated analog signal conditioning component for industrial control and measurement tasks.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin compatibility and electrical parameter alignment before replacing.
