MINI ANALOG SERIES
CMOS OPERATIONAL AMPLIFIER S-89110A/89120A
Seiko Instruments Inc. 1
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
y Lower operating voltage than the conventional general-purpose
operational amplifiers: VDD = 1.8 to 5.5 V
y Low current consumption: IDD = 50 μA (S-89110A)
I
DD = 10 μA (S-89120A)
y Low input offset voltage: 4.0 mV (max.)
y No external capaciters required for internal phase compensation
y Output full swing
y Lead-free products
Application
y Cellular phones
y PDAs
y Notebook PCs
y Digital cameras
y Digital video cameras
