LM2907MX/NOPB

Overview

The LM2907MX/NOPB is a voltage-to-frequency and frequency-to-voltage converter integrated circuit manufactured by Texas Instruments. It operates with 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 (INL) of ±1% FSR. It functions within a temperature range of -40°C to +85°C and is housed in a surface-mount SOIC-14 package.

Feature Summary

• Performs bidirectional conversion between voltage and frequency signals
• Operates on a single power supply rail
• Provides stable linear performance across the specified frequency range

Applications

• Tachometer circuits for rotational speed measurement
• Frequency modulation systems
• Digital voltmeters requiring frequency-based signal processing

Procurement Notes

Verify the specific suffix MX indicates tape-and-reel packaging versus tube variants. Confirm RoHS3 compliance status through official datasheets. Check for obsolescence notices or product change notifications regarding manufacturing location changes. Ensure the supplier provides traceable documentation matching the Texas Instruments part number exactly.

Selection Notes

Select this component when a single-supply operation is required for V/F or F/V conversion tasks. Compare against the LM2917 series if higher precision or dual-supply flexibility is needed. Consider the SOIC-14 footprint constraints during PCB layout. Verify that the 10 kHz maximum frequency meets the application bandwidth requirements.

Part Context

This device belongs to the LM2907 family of analog special function converters. It serves as a dedicated solution for converting analog voltage levels into proportional digital frequencies, or vice versa. The family is commonly used in industrial control and instrumentation applications where reliable signal translation is necessary without complex external components.
