Dual Op-Amp LM358

The Dual Op-Amp LM358 is an 8-pin integrated circuit with two independent operational amplifiers that run from a single supply, so it works well in 5 V and 12 V circuits without a negative rail. Its input range includes ground, which makes it a common choice for amplifying sensor signals and building comparators in Arduino projects.

Dual Op-Amp LM358 Specifications

• Amplifiers: 2 independent op-amps, internally frequency compensated

• Input common-mode range: includes ground (0 V)
• Unity-gain bandwidth: about 1 MHz
• DC voltage gain: about 100 dB
• Pinout: 1 OUT A, 2 IN− A, 3 IN+ A, 4 GND, 5 IN+ B, 6 IN− B, 7 OUT B, 8 VCC

Dual Op-Amp LM358 Applications

• Amplifying small signals from sensors, microphones and current shunts
• Voltage comparators and threshold detectors
• Active filters and signal conditioning for Arduino analog inputs
• Battery chargers and power supply control loops
• Electronics education and lab experiments

What's in the Box

• 1 × LM358 dual op-amp IC

Tip: The output cannot swing all the way up to the supply voltage (it stays roughly 1.5 V below VCC), so power the chip from a higher voltage than the largest output you need. Wire an unused amplifier as a voltage follower with its + input tied to ground or mid-supply to keep it stable.
