Details
The LM239AN is a quad differential comparator from the LMx39x family, designed for voltage comparisons in electronic circuits. With four independent voltage comparators featuring an open-collector output stage, it is capable of driving loads of up to 15mA. The device has an input voltage range from -0.3V to 36V, making it suitable for a wide range of voltage comparison tasks. Its low input offset voltage of 2mV ensures accurate and reliable voltage comparisons, while the low input bias current of 25nA minimizes errors in operation. The LM239AN also offers a fast response time, with a propagation delay of 1.5μs. Housed in a convenient 14-pin DIP package, it is easy to integrate into electronic designs and operates over a wide temperature range of -25°C to 85°C
Key Features
- Low input offset voltage
