Comparators are electronic components used in circuits for comparing two voltages, detecting logical levels and switching. Linear-output comparators are ideal for amplifying analog signals that are outside preset limits and providing digital output signals to a microprocessor.

The LMH7220MKX/NOPB is a linear-output comparator that is designed to meet many of the needs of today’s applications. It has a guaranteed minimum trip point accuracy and wide supply voltage range. The LMH7220MKX/NOPB has a wide operating temperature range of -40°C to +125°C and is available in a support package.

Application Field

The LMH7220MKX/NOPB can be used in a wide variety of applications, ranging from consumer electronics to industrial systems. It can be used for level-sensing applications, such as motor control, where the comparator compares the sensed level with a threshold voltage or current. It can also be used for limit-checking applications, where the comparator checks if the input voltage or current is within a preset range. Some of the other applications the LMH7220MKX/NOPB can be used for are window-comparator circuits, power-on reset generators, optocouplers, and a variety of interface circuits.

Working Principle

The LMH7220MKX/NOPB is a low-power linear-output comparator that can detect a wide range of input voltages. It is designed to operate in a single-supply operation mode; the user can select either a positive or negative output. The comparator has hysteresis, which allows the user to set the hysteresis voltage level. The hysteresis voltage level blocks false triggers from the input signal being compared to the threshold.

The LMH7220MKX/NOPB has two inputs, labeled IN+ and IN-. Input IN+ is the low-level comparator input, and input IN- is the high-level comparator input. A 10-KOhm external pull-up resistor is recommended to be connected to the high-level comparator input and an equal-valued external pull-down resistor is recommended to be connected to the low-level input for best performance. There is also an enable pin that can be used to set the enable voltage level.

The LMH7220MKX/NOPB is capable of providing a linear output voltage between 0V and the positive supply voltage. The comparator has a guaranteed maximum trip voltage accuracy and a wide supply voltage range. The module is designed to provide very low power consumption, making it ideal for portable applications.

The LMH7220MKX/NOPB is a high-performance, precision linear-output comparator that can be used in a variety of applications. It offers a wide operating temperature range, low-development costs, and low power consumption, making it an ideal choice for high-performance analog circuits.
