LM358 pin functions and connections
Signal	Type	Function & connection
OUT1	Output	Amplifier A output. Connection guidance Feed back to IN1− through Rf; connect the measured output here. Allow output headroom; do not treat it as a rail-to-rail output.
IN1−	Inverting input	Amplifier A feedback input. Connection guidance Connect the junction of Rf and Rg here. Negative feedback controls the gain while the amplifier is operating linearly.
IN1+	Non-inverting input	Amplifier A signal input. Connection guidance Connect the input signal and its common ground. Keep within the recommended common-mode range.
V−	Supply return	Lowest supply potential for both channels. Connection guidance Connect to ground in the illustrated single-supply circuit.
IN2+	Non-inverting input	Amplifier B signal input. Connection guidance In this example, connect to VIN so the spare channel acts as a buffer.
IN2−	Inverting input	Amplifier B feedback input. Connection guidance Connect directly to OUT2 for a unity-gain follower.
OUT2	Output	Amplifier B output. Connection guidance Connect to IN2−; leave the buffered output otherwise unloaded. Do not tie the two outputs together.
V+	Positive supply	Highest supply potential for both channels. Connection guidance Connect to +5 V and place a 100 nF bypass capacitor to pin 4 nearby.

Parameter	Value	Conditions / notes
Closed-loop gain	1 + Rf / Rg	Within the linear operating region
Example resistors	Rf = 20 kΩ; Rg = 10 kΩ	Gain = 3
Example input / ideal output	0.50 V / 1.50 V	Calculated, not a measured result
Explorer clipping ceiling	3.50 V	Illustrative 5 V − 1.5 V headroom
Explorer input limit	3.00 V	5 V − 2 V recommended common-mode headroom

The explorer uses a fixed DC headroom approximation. It omits offset, bias, noise, frequency, temperature and load-dependent effects.
