It is a classic tachometer building block for speed sensing, rate metering, and frequency-to-analog conversion in industrial controls, automotive instrumentation, and motor-drive feedback loops. ## Key ratings and what they mean for the BOM The 10 kHz maximum input frequency sets the practical upper bound for the pulse train this part can convert linearly. The ±0.3% linearity spec means the output voltage tracks the input frequency within that error band across the full 10 kHz span. ## Package and mounting The 14-SOIC package is a low-thermal-mass body — it heats up fast under a hot-air pencil, and the leads are exposed enough to wet with a fine-tip iron for touch-up. No hidden pads, no thermal pad underneath that wicks heat into the board. The 0.154-inch width is the narrow SOIC variant, which matches the common 3.90 mm body width. ## Lifecycle and compliance It is also RoHS3 compliant, so it meets the current EU restriction limits on lead and other substances. For new designs, this part is a safe choice without near-term supply risk. For legacy BOM lines, the active status means you can replenish without scrambling for surplus stock.","metaTitle":"LM2907MX/NOPB Frequency to Voltage Converter, 10 kHz","metaDescription":"TI LM2907MX/NOPB frequency-to-voltage converter, 10 kHz max input, ±0.3% linearity, 14-SOIC surface mount.

The closest functional sibling is the LM2917 series, which adds an internal zener regulator for a more stable reference voltage — useful if the supply rail is noisy or unregulated. Both parts share the same basic f/V core and 10 kHz maximum frequency, but the LM2917's regulated output suits automotive and industrial environments where the supply varies. Check the package variant for pin-compatibility before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2907MX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2907MX-NOPB when reusing this data.
