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.

•Operation notes
(1) Handling unused circuits
If there are any circuits which are not being used,
we recommend making connections as shown in
Figure 10, with the non-inverted input pin
connected to the potential within the in-phase
input voltage range (VICM).
