LM2917M-8

Overview

The LM2917M-8 is a monolithic integrated circuit functioning as 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 with an integral nonlinearity of +/- 1% FSR. Designed for surface-mount installation, it is housed in an SOIC-8 package. The component supports an operating temperature range from -40 C to +85 C.

Feature Summary

• Performs bidirectional conversion between voltage and frequency signals
• Operates on a single power supply configuration
• Provides high linearity performance within the specified frequency range

Applications

• Tachometer circuits
• Speed switch applications
• Frequency modulation systems

Procurement Notes

Verify the specific suffix designation when ordering, as the LM2917M-8 may be discontinued or superseded by variants such as the LM2917M-8/NOPB. Confirm RoHS compliance status and current manufacturing availability through official Texas Instruments channels or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for designs requiring precise frequency-to-voltage translation using a single-supply architecture. Ensure the input signal frequency remains within the 10 kHz limit. Verify that the SOIC-8 package dimensions fit the PCB layout constraints and that the thermal requirements align with the specified operating temperature range.

Part Context

This part belongs to the LM2917 series of data converter ICs manufactured by Texas Instruments. It is functionally related to the LM2907 but offers distinct pinout and performance characteristics tailored for modern surface-mount assembly processes. The device is categorized under Voltage to Frequency & Frequency to Voltage converters.

Replacement Considerations
