MINI ANALOG SERIES
CMOS OPERATIONAL AMPLIFIER
S-89110A/89120A
The mini-analog series is a group of ICs that incorporate a
general purpose analog circuit in a small package.
The S-89110A/89120A is a CMOS type single operational
amplifier that has 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 the ideal solution for
small battery-powered portable equipment.
The S-89110A/89120A is a single operational amplifier.
Features
Lower operating voltage than the conventional general-purpose
operational amplifiers:
Low current consumption:
Low input offset voltage:
Output full swing
