Product Overview: LM339AM/NOPB

The LM339AM/NOPB, manufactured by Texas Instruments, is a low-power, precision voltage comparator that is designed to operate from a single power supply over a wide range of voltages. This integrated circuit (IC) is characterized by its versatility and reliability, making it an excellent choice for a variety of applications, including limit comparators, simple analog to digital converters, pulse, square wave and time delay generators, and many other functions.

The device features a quad comparator configuration, which means it contains four independent precision voltage comparators in a single package, thereby saving space and improving system integration. Each comparator has been designed to directly interface with TTL, CMOS, and other logic types. This facilitates the design of mixed-technology systems and allows for a seamless integration into digital components.

The LM339AM/NOPB operates with a supply voltage range from 2V to 36V for single supply applications, or ±1V to ±18V for dual supply configurations. This wide range of operating voltages adds to the flexibility of the device, enabling it to be used in systems with varying power requirements. Additionally, the device boasts a low supply current drain, which is independent of the magnitude of the supply voltage, making it suitable for battery-powered applications and power-sensitive designs.

The device's output can drive loads connected to either power supply rail, and the open collector of the output stage makes it compatible with wired-AND logic connections. This feature allows for the direct driving of relays and lamps, and enables the outputs to be connected together for multiple functions.

The LM339AM/NOPB is also characterized by its robustness, with features such as input offset voltage compensation and differential input voltage ranges equal to the power supply voltage. It is available in a SOIC-14 package and is specified for operation over the extended industrial temperature range of -40°C to +85°C. The "NOPB" suffix indicates that this product is offered in a lead-free, RoHS-compliant package, aligning with current environmental standards for electronic components.
