LM339 – Quad Voltage Comparator (DIP14 / SOP14) ±1.5V – ±18V | Low Offset | Low Power Consumption | 0°C to +70°C | DIP14 / SOP14 Packages

The LM339 is a quad voltage comparator designed for low-power, precision voltage comparison applications. Each comparator operates independently, providing open-collector outputs suitable for both single and dual supply operation.

Operating over a wide supply range of ±1.5V to ±18V, the LM339 consumes only 1.5mA, making it ideal for battery-powered and low-power systems. It offers low input offset voltage (<±5mV) and low input bias current (<250nA), ensuring high accuracy and stability.

The LM339 is widely used in voltage monitoring, zero-crossing detection, and signal conditioning circuits. Available in DIP14 and SOP14 packages, it’s suitable for both through-hole and surface-mount designs.
