Low-frequency, micropower dual op-amp for 3 V to 32 V rails
The supply current of 54 µA for both amplifiers — 27 µA per channel — makes this a candidate for battery-powered or always-on circuits where every microamp matters. The 3 V minimum supply span lets it operate from a 3.3 V rail with headroom, while the 32 V maximum covers industrial 24 V systems without a separate preregulator. For automotive or outdoor industrial use, the industrial or extended-temperature version of the LP358 family would be needed.
A 100 kHz gain-bandwidth product means the open-loop gain drops to unity at 100 kHz. For a closed-loop gain of 10, the usable bandwidth is roughly 10 kHz. This is adequate for low-frequency transducer outputs (thermocouples, strain gauges, pressure sensors) and for DC-level shifting or active filtering below the audio band. Input offset voltage is rated at 2 mV, and input bias current at 2 nA. These are typical values for a general-purpose bipolar op-amp of this generation. For precision DC applications below 1 mV offset, a zero-drift or chopper-stabilized amplifier would be a better fit. This is enough to drive a typical ADC input, a comparator, or a low-power relay coil, but not a headphone or a motor winding. If higher drive current is needed, a buffer stage or a power op-amp should follow.
Package, mounting, and supply span decisions
The supply span range from 3 V to 32 V is a single number, meaning the part can work from a single supply (e.g., 5 V or 24 V) or from split supplies (e.g., ±1.5 V to ±16 V). The 3 V minimum is tight but usable with a 3.3 V rail — the input common-mode range and output swing near the rails should be checked against the signal levels in the specific design.
ROHS3 compliance is confirmed. No other environmental or regulatory certifications (AEC-Q, MIL-STD, etc.) are listed for this order code.
