LM2917M +BOM

This 14-pin converter conveniently translates frequency signals into voltage

LM2917M General Description

The LM2917M is a frequency-to-voltage converter integrated circuit (IC) that is designed to convert a frequency input signal into a proportional voltage output. This IC is commonly used in applications where frequency signals need to be converted into a voltage signal for monitoring or control purposes. The LM2917M operates over a wide frequency range, typically from 0.1 Hz to 10 kHz, making it suitable for a variety of different frequency input signals. It has a built-in voltage reference and an oscillator, which provides a stable and accurate conversion of the input signal into a voltage output. The output voltage of the LM2917M is directly proportional to the frequency of the input signal. The LM2917M is capable of operating with a single power supply voltage ranging from 5V to 26V, making it compatible with a wide range of power supply configurations. It also has a low current consumption of 4.5 mA, making it suitable for battery-operated applications.
