LM2917M-8/NOPB

Overview

The LM2917M-8/NOPB is a voltage-to-frequency and frequency-to-voltage converter manufactured by Texas Instruments. It operates on a single power supply ranging from 6 V to 28 V. The device features a full-scale frequency of 10 kHz with an integral nonlinearity of ±1% FSR. It is housed in an 8-SOIC surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Performs bidirectional conversion between voltage and frequency signals
• Operates on a single power supply rail
• Provides high linearity performance for precision applications

Applications

• Tachometer circuits
• Speed switch building blocks
• Frequency measurement systems

Procurement Notes

Verify the specific suffix 'M-8' against the manufacturer datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SOIC-8 package dimensions align with the PCB footprint. Confirm RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a dedicated monolithic solution for V/F or F/V conversion is needed. Consider the 10 kHz bandwidth limit and ±1% nonlinearity for accuracy requirements. Evaluate the single-supply operation against available system voltages.

Part Context

This part belongs to the LM2917 family, which includes similar devices like the LM2907. The LM2917 is specifically designed for applications requiring accurate frequency-to-voltage or voltage-to-frequency translation without external complex circuitry.

Replacement Considerations

LM2917MX-8/NOPB is a verified tape-and-reel variant of the same functional device.
