About LMV339MT/NOPB

The LMV339MT/NOPB is a rail-to-rail, low-voltage, single or dual supply comparator. This device is designed for voltage applications that require high performance. The LMV339MT/NOPB comparator has a unique feature of having rail-to-rail input, which allows it to operate from any supply voltage from 1.8V to 5.5V. It also allows for a wide input common mode range and low input offset voltage.

Application Field

The LMV339MT/NOPB is commonly used in wide range of applications, including:

• Digital-to-analog converters
• Automotive systems
• Medical electronics
• Power-supply overvoltage protection
• Threshold/trip-point detect
• Motor speed/transient detect
• Audio/Video equipments
• Processors/Level shifters
• Line termination detection

• Consumer electronics
• Mobile communication systems

In these applications, the LMV339MT/NOPB has superior performance compared to other comparators due to its wide supply and input range, fast response time and shutdown mode.

Working Principle

The LMV339MT/NOPB is a two-input comparator, based on the comparison of two voltage inputs, a positive input (Pin 2) and a negative input (Pin 3). The output of the comparator is a digital signal, with a voltage of 0V or Vcc in the respective logical states of ‘Low’ and ‘High’. When the positive input has a higher voltage than the negative input, the output is High, otherwise it is Low. The LMV339MT/NOPB has several features designed to ensure proper operation, including an output stage that drives a load current of up to 10mA, and a hysterisis of 40mV across a range of supply between 1.8V to 5.5V. An output enable control is provided with the LMV339MT/NOPB to reduce power consumption.ConclusionThe LMV339MT/NOPB comparator is a versatile, low-voltage device that is suitable for a wide range of applications. It has a rail-to-rail input, which allows for wide input common mode range, and low input offset voltage. Additionally, it features an output stage that drives a load current up to 10mA, and an output enable control that reduces power consumption. The LMV339MT/NOPB is considered an ideal choice for power-supply overvoltage protection, motor speed/ transient detect, consumer electronics, and other various fields.
