LM2917MX-8/NOPB

Overview

The LM2917MX-8/NOPB is a monolithic integrated circuit manufactured by Texas Instruments, functioning as both 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 supports a full-scale frequency of 10 kHz with an integral nonlinearity of +/- 1% FSR. It is housed in an 8-SOIC surface-mount 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
• Designed for high linearity performance

Applications

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

Procurement Notes

Verify the specific suffix '8' against the official datasheet to confirm pinout and functional compatibility. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Selection Notes

Select this component when a single-supply solution for frequency-to-voltage or voltage-to-frequency conversion is required. Consider the 10 kHz full-scale frequency limit and the +/- 1% FSR nonlinearity specification. Verify that the 6 V to 28 V operating voltage range aligns with the system power architecture.

Part Context

This part belongs to the LM2917 series of data converter ICs. It is distinct from the LM2907, which serves similar applications but may have different electrical characteristics. The '/NOPB' suffix indicates lead-free construction and absence of specific halogenated compounds, adhering to environmental standards.
