The LM2901N/NOPB is an integrated circuit (IC) component belonging to the LM2901 series of quad differential comparators. It is designed to perform analog voltage comparisons in various applications. Let's delve into its key features and functionality.
The LM2901N/NOPB IC is fabricated using low power, bipolar junction transistor (BJT) technology. It comprises four independent voltage comparators in a single package, making it highly space-efficient. These comparators have differential inputs and provide an open-collector output configuration.
One of the standout features of the LM2901N/NOPB is its wide range of supply voltage possibilities. It can operate with a voltage as low as 2V and as high as 30V, making it compatible with a diverse range of power sources. Moreover, a common-mode input voltage range of -0.3V to VCC + 0.3V enables flexible analog input signal handling.
The IC offers a high-gain differential voltage amplifier with typical values of 200,000 at 1mA (compared to the ground), allowing for precise voltage comparisons. It also exhibits low input bias current, typically around 25nA, ensuring minimal distortion during operation.
Another notable feature is the presence of built-in input hysteresis. This hysteresis enables superior noise immunity and prevents output oscillations when an input voltage is near the threshold value
