Rev.2.0_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 y Lower operating voltage than the conventional general-purpose operational amplifiers: y Low current consumption: VDD = 1.8 to 5.5 V IDD = 50 A (S-89110A) IDD = 10 A (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 Package Package Name SC-88A Drawing Code Tape NP005-B Package NP005-B Reel NP005-B Product Code List Table 1 Current consumption SC-88A IDD = 50 A S-89110ANC-1A1-TFG IDD = 10 A S-89120ANC-1A2-TFG Remark Delivery form : Taping only Seiko Instruments Inc. 1 MINI ANALOG SERIES CMOS OPERATIONAL AMPLIFIER S-89110A/89120A Rev.2.0_00 Pin Configuration SC-88A Top view VDD 5 Pin No. Symbol 1 2 3 4 5 IN(+) VSS IN(-) OUT VDD OUT 4 + - Table 2 Description Non-inverted input pin GND pin Inverted input pin Output pin Positive power supply pin Internal Equivalent Circuit Figure 3 Figure 3 Figure 2 Figure 4 2 1 3 IN (+) VSS IN (-) Figure 1 Internal Equivalent Circuit <1> Output pin <2> Input pin VDD VDD VSS VSS Figure 2 Figure 3 <3> VDD pin VDD VSS Figure 4 2 Seiko Instruments Inc.
