BA10358 / BA10358F / BA10358FV / BA10358N
The BA10358, BA10358F, BA10358FV, and BA10358N are monolithic ICs with two independent built-in operational
amplifiers featuring high gain and frequency compensation.
These products offer a particularly wide range of operating voltages, from 3 to 32V (when using a single power
supply). Current dissipation is low and remains constant regardless of the power supply voltage. Available packages
include an 8-pin DIP (BA10358), an 8-pin SOP (BA10358F), an 8-pin SSOP-B (BA10358FV), and an 8-pin SIP
(BA10358N).
Features
1) Can be driven with a single power supply.
2) Extremely low current dissipation.
3) Level is compatible with any kind of logic circuit.
4) Operating voltage range is 3 to 32V for single power
supply, ±1.5 to ±16V for dual power supply.
5) High DC voltage gain.
6) Wide frequency response.
7) Pin assignments is the same as the general-purpose
4558 model.
8) Compatible with model 358 operation amplifiers of
other manufacturers.
