Frequently Asked Questions
What is the LM2917N/NOPB and what does it do?
The LM2917N/NOPB is a monolithic frequency-to-voltage converter IC from Texas Instruments. It converts an input frequency signal into a proportional DC output voltage with a maximum linearity error of 1%, making it ideal for tachometers, speedometers, and closed-loop motor speed control systems.
What package does the LM2917N/NOPB use and is it RoHS compliant?
The LM2917N/NOPB comes in a 14-pin 0.3-inch wide DIP (Dual In-Line Package), package equivalence code DIP14,.3. The /NOPB suffix confirms it is a lead-free, RoHS-compliant device conforming to JESD-609 e4 environmental standards, suitable for modern eco-conscious designs.
What are typical applications for the LM2917N/NOPB?
Typical applications include automotive tachometers, industrial motor speed monitors, anti-lock brake system (ABS) signal processing, cruise control systems, and general frequency-to-analog conversion in instrumentation. Its integrated comparator output stage allows direct relay or LED driving without extra components.
What is the linearity specification of the LM2917N/NOPB?
The LM2917N/NOPB specifies a maximum linearity error (EL) of 1%, meaning the output voltage is highly proportional to the input frequency across the operating range. This precision makes it suitable for accurate speed measurement and control loops requiring consistent analog representation of frequency.
Are there alternative or drop-in replacements for the LM2917N/NOPB?
Common alternatives to the LM2917N/NOPB include the LM2907 series (frequency-to-voltage converter without internal Zener reference), and the LM2917-8 in 8-pin DIP for space-constrained designs. Always verify supply voltage range, output current capability, and pin compatibility before substituting in an existing design.
