T
The mini analog series is a group of ICs that incorporate a
general-purpose analog circuit in a small package.
The S-89410A is a CMOS type middle-band operational
amplifier that includes a phase compensation circuit and
that can be driven at a lower voltage with lower current
consumption than existing bipolar operational amplifiers.
These features make this product ideal for use in small
battery-powered portable equipments.
