The LM2901M\/NOPB is a quad differential comparator from Texas Instruments, packaged in a 14-pin SOIC (M) package. It is designed to operate from a single power supply over a wide range of 3V to 36V, with an open-collector output configuration. The device features a common-mode input voltage range that includes ground, making it ideal for ground-referenced signal comparison.<\/p>\n

It contains four independent comparators, each with an open-collector output that can be connected to voltages up to 36V regardless of the supply voltage, enabling level translation and wired-OR logic. The input common-mode voltage range includes ground, allowing ground-referenced signal comparison without additional bias circuitry. The LM2901M variant in SOIC-14 package offers robust performance for automotive and industrial environments.","working_principle":"Each comparator in the LM2901 consists of a differential input stage, gain stages, and an open-collector output transistor. The differential input stage compares the voltage at the non-inverting input (+) with the voltage at the inverting input (-). When the non-inverting input voltage exceeds the inverting input, the internal output transistor turns off, allowing the open-collector output to be pulled high by an external pull-up resistor. When the inverting input is higher, the output transistor turns on, pulling the output low. The open-collector configuration enables wired-OR connections where multiple comparator outputs can share a single pull-up resistor, generating a logic OR function. The output can also be pulled up to a voltage different from the supply, facilitating level translation.","pin_description":"
