The LM339ADRG4 is a quad differential comparator integrated circuit (IC) component designed and manufactured by Texas Instruments. It is widely used in various electronic applications requiring precision and accuracy in comparing analog voltage levels. Here's an overview and key features of the LM339ADRG4:
1. Functionality: The LM339ADRG4 consists of four independent voltage comparators integrated into a single package. Each comparator provides an open-drain output that can be directly connected to a variety of logic devices, allowing easy interfacing with digital circuits.
2. Input and Output Range: This IC has four input pins (IN- and IN+) per comparator, where IN- is the inverting input and IN+ is the non-inverting input. The input voltage range extends from the negative supply voltage (V-) to the positive supply voltage (V+). The output terminal (OUT) provides a low impedance, open-collector output that can be externally pulled-up to the desired voltage level.
3. Low Power Consumption: The LM339ADRG4 operates on a low supply voltage, typically ranging from 2 V to 36 V. It consumes minimal power (typically around 0.8 mW per comparator) and is suitable for low-power applications, making it an energy-efficient solution.
4. Wide Common-Mode Voltage Range: The common-mode voltage range (Vicm) is the range in which the comparator can accurately distinguish between high and low input levels
