LM239N - DIP

The LM239 is a 14-pin dual in-line package (PDIP) integrated circuit (IC) that functions as a differential comparator. It is designed to compare voltage differences between two inputs and provide digital outputs based on the comparison.

The LM239 contains four comparator elements, allowing for multiple differential comparisons within a single IC. It supports output types of open-collector and rail-to-rail, providing flexibility in terms of output configurations.

The IC can be powered by a single supply voltage ranging from 2V to 30V or dual supplies with a voltage range of ±1V to ±15V. This wide voltage supply range enables its usage in various power systems.

To ensure accurate comparisons, the LM239 has a maximum input offset voltage of 5mV when operated with a 30V supply. It exhibits low input bias current, with a maximum of 0.25µA when subjected to a 5V input voltage.

The LM239 has a typical output current of 20mA, allowing it to drive external loads effectively. It has a maximum quiescent current of 2mA, ensuring efficient power usage.

Although specific values for characteristics such as propagation delay, hysteresis, common mode rejection ratio (CMRR), and power supply rejection ratio (PSRR) are not provided, the LM239 can be expected to deliver typical performance for a differential comparator.

The IC operates reliably over a temperature range of -25°C to 85°C. Its 14-DIP package with a lead spacing of 0.300 inches (7.62 mm) facilitates through-hole mounting, making it suitable for integration into various electronic systems.

Overall, the LM239 is a differential comparator IC that can compare voltage differences between inputs and provide digital outputs. With its multiple comparator elements, wide supply voltage range, low input offset voltage, and low input bias current, it is suitable for a range of applications where accurate differential voltage comparisons are required.
