LM2907M

Overview

The LM2907M is a frequency-to-voltage converter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 6 V to 28 V and supports single-supply configurations. The device features a full-scale frequency capability of 10 kHz with an integral nonlinearity (INL) of ±1% FSR. It is housed in a 14-SOIC surface-mount package and functions across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Performs conversion of input frequency signals into proportional analog voltage outputs
• Provides linear error performance specified at ±1% of full-scale range
• Supports operation with a single power supply source

Applications

• Tachometer circuits for rotational speed measurement
• Speed switch building blocks
• Frequency demodulation systems

Procurement Notes

Verify component status carefully as the LM2907M is listed as obsolete or end-of-life by multiple distributors. Confirm availability through authorized channels and check for active replacement part numbers such as the LM2907M-8/NOPB or LM2907M/NOPB before finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when a dedicated frequency-to-voltage conversion function is required for low-frequency signals up to 10 kHz. Ensure the design accommodates the 14-pin SOIC footprint and that the system power supply remains within the 6 V to 28 V operational limits. Verify that the ±1% FSR linearity meets the specific application accuracy requirements.

Part Context

This device belongs to the LM2907 family of analog special function converters designed for signal processing tasks involving frequency modulation. It serves as a specialized solution for converting periodic signals into DC levels, distinct from general-purpose operational amplifiers or standard voltage regulators found in other Texas Instruments product lines.

Replacement Considerations

Direct substitutes include LM2907M-8/NOPB and LM2907M/NOPB. Verify pin compatibility and package dimensions before substitution.
