LM2917M/NOPB

Overview

The LM2917M/NOPB is a frequency-to-voltage and voltage-to-frequency converter manufactured by Texas Instruments. It operates on a single power supply ranging from 6 V to 28 V. The device features a full-scale frequency of 10 kHz with an integral nonlinearity of +/- 1% FSR. It is housed in a 14-pin SOIC package and supports surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between frequency and voltage signals
• Operates on a single power supply configuration
• Provides high linearity performance for signal processing

Applications

• Tachometer circuits
• Speed control systems
• Frequency modulation demodulation

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the SOIC-14 package dimensions match your PCB footprint requirements. Ensure the operating voltage remains within the 6 V to 28 V range to maintain specified accuracy and prevent damage. Check for any recent product change notices regarding assembly or sourcing updates.

Selection Notes

Select this component when precise frequency-to-voltage conversion is required for industrial or automotive applications. Consider the 10 kHz full-scale limit and +/- 1% nonlinearity against your system's accuracy needs. Evaluate the SOIC-14 package for thermal management and board space constraints. Compare against other converters if higher frequencies or different supply voltages are necessary.

Part Context

This part belongs to the LM2917 series, which includes variants like the LM2917MX-8/NOPB in an 8-SOIC package. The family offers similar functional capabilities but differs in pin count and physical footprint. The LM2917M/NOPB specifically utilizes a 14-pin configuration, distinguishing it from the 8-pin versions while maintaining core conversion characteristics.

Replacement Considerations

Direct substitutes include other LM2917 variants such as LM2917N (DIP) or LM2917MX-8/NOPB (SOIC-8), provided pin compatibility and package size allow for integration without redesigning the circuit layout.
