... LM9022 Vacuum Fluorescent Display Filament Driver General Description The LM9022 is a bridged power amplifier capable of deliv- ering typically 2W of continuous average power into a 10Ω filament load when powered power supply. To conserve power in portable applications, the LM9022’s micropower shutdown mode (I = 0.6µ ...

... Typical applications will require both a 22µf electrolyte and a 0.1µF ceramic capacitor to bypass the supply pin to ground. These capacitors should be as close to the LM9022 as is physically possible, and are in addition to any capacitors that may be needed for regulator stability. ...
