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 10
filament load when powered by a 5V power supply.
To conserve power in portable applications, the LM9022’s
micropower shutdown mode (I
= 0.6μA, typ) is activated
when V
DD
is applied to the SHUTDOWN pin.
Additional LM9022 features include thermal shutdown pro-
tection, unity-gain stability, and external gain set.
