LM301A pin functions and connections
Signal	Type	Function & connection
BAL1	Balance / compensation	One balance node also used by the external compensation network. Connection guidance Connect a 30 pF capacitor to pin 8 in this example. Do not leave the compensation path out.
IN−	Inverting input	Negative-feedback input. Connection guidance Join the 90 kΩ feedback and 10 kΩ ground resistors.
IN+	Non-inverting input	Positive signal input. Connection guidance Apply 0.20 V relative to the supply midpoint.
VEE	Negative supply	Negative power rail. Connection guidance Connect to −15 V and bypass to the 0 V midpoint.
BAL2	Balance	Other offset-balance node. Connection guidance Leave open when optional offset adjustment is not fitted.
OUT	Analog output	Class AB amplifier output. Connection guidance Connect 90 kΩ to IN− and a high-impedance meter. Not rail-to-rail.
VCC	Positive supply	Positive power rail. Connection guidance Connect to +15 V and bypass locally to midpoint.
COMP	Compensation	External frequency-compensation connection. Connection guidance Connect 30 pF between pins 8 and 1. This pin is functional; it is not NC as on some other eight-pin amplifiers.

Scroll within the table to see all columns and rows.

Parameter	Value	Conditions / notes
Positive / negative rails	+15 V / −15 V	Pins 7 / 4; midpoint is 0 V
Compensation	30 pF	Between pins 1 and 8
Feedback / return	90 kΩ / 10 kΩ	OUT6 to IN−2; IN−2 to midpoint
Input / ideal output	0.20 V / 2.00 V	IN+3; high-impedance output meter
Supply bypass	100 nF per rail	Each rail to midpoint
Balance pin 5	Open	Optional trim not fitted

30 pF is a conservative standard compensation choice; dynamic behavior still needs validation.
