LM331N – Precision Voltage-to-Frequency Converter IC

MPN:LM331N

The LM331N is a precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter IC originally developed by National Semiconductor. It converts an analog input voltage into a proportional frequency output with high linearity and stability. The LM331N is widely used in analog-to-digital conversion, telemetry, signal conditioning, and sensor interfacing. The N suffix indicates a DIP (through-hole) package, suitable for prototyping and industrial applications.
