P1 (Pin 1): Noninverting Gain-of-1 Input. Connects a 4k
internal resistor to the op amp’s noninverting input.
P2 (Pin 2): Noninverting Gain-of-2 Input. Connects a 2k
internal resistor to the op amp’s noninverting input.
P4 (Pin 3): Noninverting Gain-of-4 Input. Connects a 1k
internal resistor to the op amp’s noninverting input.
