Overview
The LM2917MX-8/NOPB is a frequency-to-voltage converter integrated circuit manufactured by Texas Instruments. It operates on a single power supply ranging from 6 V to 28 V and functions within an industrial temperature range of -40°C to +85°C. The device features a full-scale frequency capability of 10 kHz with an integral nonlinearity of ±1% FSR. It is housed in an 8-SOIC surface-mount package, designed for applications requiring precise conversion of input pulse frequencies into proportional analog voltage outputs.
Feature Summary
- Performs frequency-to-voltage conversion using a single-supply architecture
- Provides linear output voltage proportional to input signal frequency
- Operates reliably across extended industrial temperature ranges
Applications
- Tachometer circuits for rotational speed measurement
- Speed switch building blocks
- Frequency demodulation systems
Procurement Notes
Verify the specific suffix (e.g., MX-8/NOPB) against the required datasheet revision and RoHS compliance status. Confirm that the SOIC-8 package dimensions match the target PCB footprint. Ensure the operating voltage and temperature requirements align with the system specifications before finalizing procurement orders.
Selection Notes
Select this component when a dedicated frequency-to-voltage conversion function is required without external complex timing networks. Consider the 10 kHz bandwidth limit and ±1% nonlinearity for accuracy requirements. Compare against the LM2907 series if voltage-to-frequency conversion or different pinout configurations are needed for the specific application design.
Part Context
This part belongs to the LM2917 family of frequency-to-voltage converters. It serves as the surface-mount counterpart to through-hole variants like the LM2917M. The device integrates internal comparators and timers to convert input pulses directly into a DC voltage level proportional to the input frequency.
Replacement Considerations
LM2917MX-8/NOPB is the direct lead-free replacement for older versions. LM2907MX-8/NOPB is a related frequency-to-voltage converter but may require schematic adjustments due to functional differences.
