LM2901DRG4 Typical application Circuitry

LM2901DRG4

The LM2901DRG4 is part of Texas Instruments' LM2901 series, which comprises low-power quad differential comparators. These comparators are designed for applications where the ability to compare different voltage inputs is necessary, such as in control systems, and they are characterized by their wide supply voltage range and low supply current.

1. Pins 2, 3, 6, 7, 10, and 11 (Inverting Inputs): Each of these pins serves as the inverting input to one of the four comparators. You would connect the reference voltage or the voltage you want to compare against to these pins.

2. Pins 1, 5, 8, and 9 (Non-inverting Inputs): These pins are the non-inverting inputs for the comparators. The voltage you wish to compare will be connected here.

3. Pins 4 and 13 (GND/VCC-): Pin 4 is typically connected to the ground reference of the system. For single-supply operations, pin 13 is also connected to ground. In dual-supply applications, pin 13 would be connected to the negative voltage.

4. Pins 12 and 14 (VCC+/VCC): Pin 14 is linked to the voltage of the positive supply. In a single-supply operation, this would be your sole supply voltage. For dual-supply systems, pin 12 would be connected to the positive voltage.

5. Pins 1, 5, 8, and 9 (Output): These pins are the outputs for each of the four comparators. The output can be connected to the next stage in your circuit, which could be logic input, an LED for indication, or another part of a control system.

When using the LM2901DRG4, it's important to set up the inputs with the correct voltage levels that you wish to compare. You may also need to include pull-up resistors on the outputs, as the outputs of the LM2901 are open-collector. This means they need an external resistor to pull the output high when the comparator is not driving it low. The datasheet for the LM2901DRG4 will provide detailed information on the required voltage levels, hysteresis, biasing, and other design considerations. Additionally, decoupling capacitors close to the power supply pins are recommended to filter noise and stabilize the supply voltage. Following these guidelines will help ensure that the LM2901DRG4 operates effectively as a comparator in your electronic designs.
