LM211D SO-8 Differential Analog Comparator

The LM311D is a low-power differential analog comparator. It is an integrated circuit (IC) that can be used to compare two analog signals and generate a digital output. It has two inputs, a reference input and a signal input. The reference input is a fixed voltage, while the signal input can vary.

When the signal applied to the signal input is greater than the signal applied to the reference input, the LM311D generates a high output. When the signal applied to the signal input is less than the signal applied to the reference input, the LM311D generates a low output.

Here are some technical specifications of the LM311D:

• Supply voltage: 3.3V – 30V
• Dropout voltage: 1.2V
• Output current: 10mA
• Rise time: 20 ns
• Fall time: 20 ns
• Gain: 100V/V
• Input sensitivity: 10mV

The LM311D is a relatively inexpensive and easy-to-use component. It is a good choice for applications requiring a low-power analog comparator.

[title] - Electronic comparators are devices that compare two analog signals and generate a digital output that indicates which signal is greater. They are versatile electronic components that can be used in a variety of applications, including Switch control, Event Detection, Signal filter.

It usually consists of two inputs and one output. The inputs are used to connect analog signals to be compared. The output indicates which signal is greater. When the voltage on the positive input of the comparator is greater than the voltage on the negative input, the comparator output is high. When the voltage on the negative input of the comparator is greater than the voltage on the positive input, the comparator output is low.

There are two main types of electronic comparators: Threshold comparators (with a specific threshold voltage. When the voltage at one of the comparator inputs exceeds the threshold voltage, the comparator output changes state), Window comparators (They have two threshold voltages. When the voltage at one of the comparator inputs is between the two threshold voltages, the comparator output is high. When the voltage at one of the comparator inputs is outside the two threshold voltages, the comparator output is low.)
