LM2917M

Overview

The LM2917M 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 and an integral nonlinearity (INL) of +/- 1% FSR. It is housed in a SOIC-14 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 with a single power supply configuration
• Provides high accuracy with low integral nonlinearity

Applications

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

Procurement Notes

Verify the specific ordering suffix, such as NOPB, which indicates lead-free compliance and RoHS adherence. Confirm the package type matches the required SOIC-14 footprint for PCB layout. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for reliable performance.

Selection Notes

Select this component when precise linear conversion between analog voltage levels and digital frequency pulses is required. It is suitable for applications demanding a wide dynamic range and stable operation under varying supply voltages. Consider the SOIC-14 package size for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the LM2917 series of data converter ICs designed for signal conditioning tasks. It serves as a core building block for industrial control and instrumentation systems where frequency-based transmission or measurement is preferred over analog voltage handling due to noise immunity.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family that may offer updated packaging or environmental certifications. Verify electrical parameter equivalence before substitution to ensure circuit functionality remains unchanged.
