Rev.1.1_10 MINI ANALOG SERIES CMOS SINGLE WIDE-BAND OPERATIONAL AMPLIFIER S-89402A/89403A Series The mini analog series is a group of ICs that incorporate a general-purpose analog circuit in an ultra-small package. The S-89402A and S-89403A series are CMOS type wide-band operational amplifiers with a 10 MHz gain-bandwidth product (GBP) and can be used in a negative feedback circuit with five times or more gain. Since these products can be driven at a lower voltage with lower current consumption than existing bipolar operational amplifiers, they are ideal for use in small battery-powered portable equipment.

Use a gain of five times or more. Be aware that, as in the majority of other operational amplifiers, the capacitative load reduces the phase margin, which may cause ringing, overshoot, or inadvertent oscillation even if the gain is five times or more. * Be sure to use the product with an output current of no more than 30 mA.
