LM9022 Vacuum Fluorescent Display Filament Driver
General Description
The LM9022 is a bridged power amplifier capable of delivering typically 2W of continuous average power into a 10Ω filament load when powered by a 5V power supply.
To conserve power in portable applications, the LM9022’s micropower shutdown mode (IQ = 0.
6µA, typ) is activated when VDD is applied to the SHUTDOWN pin.
Additional LM9022 features include thermal shutdown protection, unity-gain stability, and external gain set.
