LM2917MX/NOPB

Overview

The LM2917MX/NOPB is a frequency-to-voltage converter manufactured by Texas Instruments, housed in an SOIC-14 surface-mount package. It operates on a single power supply ranging from 6 V to 28 V and supports full-scale frequencies up to 10 kHz. The device exhibits an integral nonlinearity of +/- 1% FSR. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs conversion of input frequency signals into proportional analog voltage outputs
• Designed for ground-referenced frequency input applications
• Operates with a single power supply configuration

Applications

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

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics match the required design specifications. Ensure the SOIC-14 package dimensions align with the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated frequency-to-voltage conversion function is required rather than using a general-purpose operational amplifier. The integrated design simplifies circuit topology compared to discrete solutions. Verify that the 10 kHz maximum frequency and 1% nonlinearity meet the precision requirements of the specific application environment.

Part Context

This part belongs to the LM2917 series of data converters. It serves as a specialized integrated circuit for signal conditioning tasks involving frequency inputs. The device is distinct from voltage-to-frequency converters like the LM2907, offering complementary functionality within the same product family for bidirectional signal conversion needs.
