The NJM2903M is a dual comparator integrated circuit. It typically comes in an 8-pin package. Here’s a brief overview of its pin configuration and functions:
1. Pin 1 (OUT A): Output of Comparator A.
2. Pin 2 (IN- A): Inverting input of Comparator A.
3. Pin 3 (IN+ A): Non-inverting input of Comparator A.
4. Pin 4 (GND): Ground, the negative power supply terminal.
5. Pin 5 (IN+ B): Non-inverting input of Comparator B.
6. Pin 6 (IN- B): Inverting input of Comparator B.
7. Pin 7 (OUT B): Output of Comparator B.
