LM339PWR  

Linear Comparators

The LM339PWR is a high-performance, wide operating voltage comparator from Texas Instruments. It is designed to operate over a wide range of supply voltages, making it suitable for various applications.

Description:

The LM339PWR is a quad comparator, which means it has four independent comparators in a single package. It is available in a 14-pin dual in-line package (DIP) or a 14-pin small outline package (SOP). The comparators have a differential input voltage range that extends to the negative supply voltage, allowing them to operate with a single supply or split supplies.

Features:

1. Wide operating voltage range: The LM339PWR can operate with supply voltages ranging from ±1.5V to ±36V, making it suitable for a wide range of applications.
2. High input voltage range: The input voltage range extends to the negative supply voltage, allowing the comparators to operate with a single supply or split supplies.
3. Short-circuit protection: The LM339PWR has built-in short-circuit protection for the output, which helps prevent damage to the device in case of a short circuit.
4. Low input offset voltage: The input offset voltage is typically ±2mV, which is low compared to other comparators, ensuring high accuracy in applications that require precise voltage comparisons.
5. Low power consumption: The LM339PWR has a low power consumption of typically 4.5mA per comparator, making it suitable for battery-powered applications.
6. Rail-to-rail input: The input voltage range extends to the supply rails, allowing the comparator to accurately compare voltages close to the supply voltages.

Applications:

1. Voltage level detection: The LM339PWR can be used to detect when a voltage reaches a certain level, triggering an output signal.
2. Signal amplification: The comparators can be used to amplify small voltage differences, making them more suitable for further processing or driving larger loads.
3. Pulse generation: The LM339PWR can generate pulses based on voltage level changes, which can be used in various control applications.
4. Battery monitoring: The wide operating voltage range and low power consumption make the LM339PWR suitable for monitoring battery voltage levels in portable devices.
5. Industrial control: The LM339PWR can be used in various industrial control applications, such as motor control, temperature monitoring, and process control.
6. Medical equipment: The LM339PWR can be used in medical equipment for monitoring and controlling various parameters, such as blood pressure, temperature, and heart rate.

In summary, the LM339PWR is a versatile and high-performance comparator from Texas Instruments, suitable for a wide range of applications due to its wide operating voltage range, low input offset voltage, and low power consumption.
