LM2907N

Overview

The LM2907N-8/NOPB is a monolithic integrated circuit manufactured by Texas Instruments, functioning as both a voltage-to-frequency and frequency-to-voltage converter. It operates on 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 of ±1% FSR. It is housed in an 8-pin PDIP package and is designed for through-hole mounting. The operational temperature range extends from -40°C to +85°C.

Feature Summary

• Provides dual functionality for converting input voltage signals into proportional frequency outputs and vice versa.
• Operates reliably using a single power supply source within the specified voltage limits.
• Delivers consistent linearity performance across the designated frequency range.

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Ensure the ordering code matches the required package type and temperature grade. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a single-supply solution for frequency conversion is required. Consider the 10 kHz full-scale limit and ±1% nonlinearity for accuracy requirements. Evaluate the PDIP-8 package suitability for the target PCB layout and thermal management needs compared to surface-mount alternatives.

Part Context
