LM2907MX-8

Overview

The LM2907MX-8 is a frequency-to-voltage converter manufactured by Texas Instruments, housed in an 8-SOIC 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 and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs conversion between input frequency signals and proportional output voltage levels
• Designed for ground-referenced signal applications
• Integrated circuit implementation suitable for compact surface-mount designs

Applications

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

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation, as the 'MX' designation indicates a tape-and-reel packaging variant distinct from tube-packaged versions like the LM2907M. Confirm RoHS compliance status via the manufacturer's current datasheet, as environmental declarations may vary by production batch or revision. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target application design.

Selection Notes

Select this component when a monolithic solution for frequency-to-voltage conversion is required with moderate linearity and wide supply voltage tolerance. Consider the 8-SOIC package constraints for PCB layout and thermal management. Evaluate the +/- 1% FSR nonlinearity against system accuracy requirements before finalizing the design.

Part Context

This device belongs to the LM2907 series of frequency-to-voltage converters. It serves as a direct replacement for older plastic packages such as the LM2907M-8, offering improved manufacturing consistency through modern semiconductor processes while maintaining functional compatibility with legacy designs.

Replacement Considerations

LM2907MX-8/NOPB is a verified direct replacement offering identical functionality with updated environmental compliance.
