LM2907MX

Overview

The LM2907MX is a frequency-to-voltage converter integrated circuit manufactured by Texas Instruments. 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 features an integral nonlinearity of +/- 1% FSR and functions within a temperature range of -40°C to +85°C. It is housed in an SOIC-8 surface-mount package.

Feature Summary

• Performs conversion between input frequency signals and proportional output voltage levels
• Operates using a single power supply configuration for simplified circuit design
• Provides stable performance across industrial temperature ranges

Applications

• Tachometer systems for rotational speed measurement
• Speed switch building block applications
• Frequency monitoring circuits

Procurement Notes

Verify the specific suffix against official documentation, as variations such as MX-8/NOPB or standard MX/NOPB may exist with different pin counts or packaging. Confirm RoHS compliance status and ensure the selected variant matches the required package type for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a dedicated frequency-to-voltage conversion function is required within a compact surface-mount footprint. Ensure the input signal frequency remains within the specified 10 kHz limit and that the supply voltage stays between 6 V and 28 V to maintain accurate linearity and operational stability.

Part Context

This part belongs to the LM2907 series of data converters designed for analog signal processing tasks involving frequency modulation. It serves as a specialized building block for instrumentation requiring precise translation of periodic signals into DC voltage levels for further analog processing or display.

Replacement Considerations

Public confirmed substitute part numbers include LM2907M-8/NOPB and LM2907MX-8/NOPB.
