Industry-standard dual operational amplifier in a SOIC-8 package. Two independent op-amps share the V+/V- rails and run from a wide 3-30 V single or split supply, with a common-mode input range that includes ground for direct single-supply sensing near 0 V. Gain-bandwidth is 0.7-1.2 MHz and outputs are class-AB, short-circuit protected. A default choice for signal conditioning, active filters, and sensor front-ends.

Pinout

Pin	Name	Type	Function
1	OUT1	output	Output of amplifier 1. Class-AB output stage; can source ~20–30 mA and sink ~10–20 mA; short-circuit protected. Swings from V− up to within ~1.5 V of V+ (Vs=15V, RL=2kΩ).
2	IN1-	input	Inverting (negative) input of amplifier 1. High-impedance input (Zid ≈ 10 MΩ). Input bias current typ. −20 nA (max −250 nA for LM358). Differential input voltage range ±32 V.
3	IN1+	input	Non-inverting (positive) input of amplifier 1. Common-mode input range includes V− (ground) up to (V+)−1.5 V, enabling direct single-supply ground sensing.
4	V-	power_in	Negative (lowest) supply rail, or ground for single-supply operation. Total supply Vs = (V+)−(V−) = 3 V to 30 V (LM358/A) or 3 V to 36 V (LM358B/BA). Common ground reference for both amplifiers.
5	IN2+	input	Non-inverting (positive) input of amplifier 2. Common-mode range V− to (V+)−1.5 V; input bias current typ. −20 nA.
6	IN2-	input	Inverting (negative) input of amplifier 2. High-impedance input, Zid ≈ 10 MΩ. Differential input voltage range ±32 V.
7	OUT2	output	Output of amplifier 2. Class-AB output; source ~20–30 mA, sink ~10–20 mA; short-circuit protected; swings to within ~1.5 V of V+ and to ~5–20 mV of V− with light load.
8	V+	power_in	Positive (highest) supply rail. Vs = 3 V to 30 V (LM358/A) or 3 V to 36 V (LM358B/BA). Quiescent current typ. 300–350 µA per amplifier (600–800 µA total). Bypass with 100 nF to V−.
