The LMV339MTX/NOPB is part of the Comparators family from Texas Instruments, a semiconductor technology company. The LMV339MTX/NOPB is a low-power, dual comparator and provides excellent accuracy with excellent Hysteresis and response time. It is suitable for a wide range of applications, including applications that require short settling time, robust noise and output signal customization, and voltage or current mode operation.

The application fields of the LMV339MTX/NOPB are generic switches and as a signal conditioning device in consumer, industrial, computer and communication applications. It is especially suitable for use in power supplies, motor control, HVAC systems and consumer appliances. The comparator can also be used to obtain an output signal (capable of driving a Darlington transistor) upon detecting a predetermined input signal.

The working principle of the LMV339MTX/NOPB is simple and relies on comparing two input signals using two differential amplifiers and generating two opposite logic-level outputs. The comparator uses three primary components: a bias voltage, an inverting amplifier, and a non-inverting amplifier. The non-inverting amplifier receives one of the signals to compare (e.g. an analog input signal or a reference voltage) and applies it to its inverting input. The inverting amplifier is then used to receive the second signal, or ‘reference’ signal and applies it to its non-inverting input.

The bias voltage is used to adjust the response time of the comparator and other parameters, such as its settling time and input impedance. Depending on the level of the input signals, the bias voltage is adjusted in such way that one of the two output transistors is turned on (producing a logic-level output) while the other is turned off.

The LMV339MTX/NOPB features integrated protection against over-voltage, molten feedthrough and glitching. This protection reduces the risk of damage associated with misapplication of the device, as well as helping to protect the device from potential power disturbances. The LMV339MTX/NOPB can also support multiple input configurations, such as single-ended or push-pull, which provides the flexibility to interface with various external components. This enables the LMV339MTX/NOPB to be used in applications with differences in the power supplies and internal components.

The LMV339MTX/NOPB is specially designed to provide excellent accuracy, fast response time and low-power consumption. The device is also ideal for applications that require robust noise immunity, customization of output signals, and/or voltage or current mode operation. It is versatile, easy to set up, reliable and cost-effective, making it a great choice for many different applications.
