LM2901DR Typical application Circuitry

LM2901DR

The LM2901DR is part of the LM2901 series, which encompasses quad differential comparators. These devices can drive a range of outputs, from TTL to MOS, and are made to run off a single power source across a wide voltage range. They are commonly utilized in circumstances when several voltage comparisons are required.

1. Pin 1 (Output 1): The first comparator's output is connected to this pin. It will be high or low depending on the result of comparing the voltages on the inverting and non-inverting inputs of the first comparator.

2. Pin 2 (Inverting Input 1): Connect this pin to the reference voltage or signal that the non-inverting input of comparator 1 will be compared against.

3. Pin 3 (Non-Inverting Input 1): This pin is the non-inverting input of the first comparator and should be connected to the signal voltage you wish to compare.

4. Pin 4 (VCC-): Also known as GND in single-supply operations, this pin is typically connected to the system ground.

5. Pin 5 (Non-Inverting Input 2): This is the second comparator's non-inverting input.

6. Pin 6 (Inverting Input 2): Connect this pin to the reference voltage or signal for comparator 2.

7. Pin 7 (Output 2): Output of the second comparator.

8. Pin 8 (Non-Inverting Input 3): Non-inverting input for the third comparator.

9. Pin 9 (Inverting Input 3): Inverting input for comparator 3.

10. Pin 10 (Output 3): Output of comparator 3.

11. Pin 11 (Output 4): Output of the fourth comparator.

12. Pin 12 (Inverting Input 4): Inverting input for comparator 4.

13. Pin 13 (Non-Inverting Input 4): Non-inverting input for the fourth comparator.

14. Pin 14 (VCC+): This is the device's positive supply voltage. In single-supply operations, this is where the positive voltage is applied.

When integrating the LM2901DR into your design, it is crucial to select the power supply voltage that matches the desired logic level of the output. Capacitors may be added at the power supply pin for stability. The inputs can be configured depending on whether you are comparing against a fixed reference voltage or varying signal levels. The output can be connected to digital logic circuits, an LED for visual indication, or other interfaces as required by your application. The LM2901DR can operate across a broad spectrum of voltages, making it versatile for various scenarios. Proper bypassing and decoupling techniques should be employed to maintain signal integrity and stability of the comparator. Following these guidelines will ensure that the LM2901DR performs optimally in voltage comparison applications.
