S-89431A

Rev.5.1_00 MINI ANALOG SERIES 0.5 μA Rail-to-Rail CMOS OPERATIONAL AMPLIFIER S-89430A/89431A The mini-analog series is a group of ICs that incorporate a general purpose analog circuit in a small package. The S-89430A/89431A is a CMOS type operational amplifier that feature Rail-to-Rail*1 I/O and an internal 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. These features enable driving at a lower voltage (from 0.9 V) and with lower current consumption (0.5 μA) The S-89430A/89431A is a single operational amplifier. *1. Rail-to-Rail is a registered trademark of Motorola Inc. Features Lower operating voltage than the conventional general-purpose operational amplifiers: VDD = 0.9 to 5.5 V Low current consumption: Wide I/O voltage range: ( Rail-to-Rail ) Low input offset voltage: 10.0 mV (max.)
