LM2907M-8

Overview

The LM2907M-8 is a discontinued frequency-to-voltage converter IC manufactured by Texas Instruments. It operates within a supply voltage range of 6 V to 28 V and supports a full-scale frequency of 10 kHz. The device features an integral nonlinearity of ±1% FSR and is housed in an 8-pin SOIC package. It functions as a single-supply component suitable for surface-mount installation.

Feature Summary

• Interfaces directly with variable reluctance magnetic pickups via ground-referenced tachometer input
• Integrates an operational amplifier with a floating transistor output

Applications

• Tachometer circuits
• Speed switch building blocks

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of active substitutes such as the LM2907M-8/NOPB or LM2907MX-8/NOPB. Ensure design updates accommodate any pinout or electrical differences between legacy and current generation components to maintain system compatibility.

Selection Notes

Select this component only if legacy design constraints require the specific LM2907M-8 form factor. For new designs, evaluate the LM2907M-8/NOPB or LM2907MX-8/NOPB as direct replacements. Consider the 10 kHz frequency limit and ±1% FSR linearity when matching application requirements against available active inventory options.

Part Context

This device belongs to the LM2907 family of voltage-to-frequency and frequency-to-voltage converters. It is designed for applications requiring precise conversion between frequency signals and analog voltage levels.
