S-89110A

Rev.2.2_00 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 Lead-free products VDD = 1.8 to 5.5 V IDD = 50 μA (S-89110A) IDD = 10 μA (S-89120A) 4.0 mV (max.)
