Summary
Dual operational amplifier IC. Two independent, internally-compensated op-amps in one chip, designed to run off a single supply — the classic choice for comparators, sensor amplification, and signal conditioning in beginner analog circuits.
- Supply voltage (single supply): 3V - 32V
- Supply voltage (dual supply): ±1.5V - ±16V
- Output current per channel: ~20mA (source/sink)
- Gain bandwidth product: 0.7MHz (typ, LM358/LM358A)
- Input offset voltage: 2mV typ / 7mV max
