Description

AO4478 Overview
As an op amp's input capacitance parameter, CI, is defined as the capacitance between the input terminals when one input is grounded, this device's maximum input capacitance is 560pF @ 15V.This device conducts a continuous drain current (ID) of 9A, which is the maximum continuous current transistor can conduct.This transistor requires a drain-source voltage (Vdss) of 30V.In order to reduce power consumption, this device uses a drive voltage of 4.5V 10V volts (4.5V 10V).

AO4478 Features
a continuous drain current (ID) of 9A
a 30V drain to source voltage (Vdss)
