Part Details:

LM9022 August 2005 V LM9022 acuum Vacuum Fluorescent Display Filament DriverGeneral Description Key Specifications Fluorescent The LM9022 is a bridged power amplifier capable of deliv- n I during shutdown 0.6µA (typ) DD ering typically 2W of continuous average power into a 10 n Thermal Shutdown Protection filament load when powered by a 5V power supply. To conserve power in portable applications, the LM9022 s Features micropower shutdown mode (I = 0.6µA, typ) is activated Q n No transformers required when V is applied to the SHUTDOWN pin. DD n SO or DIP packaging Additional LM9022 features include thermal shutdown pro-tection, unity-gain stability, and external gain set. Applications Display n VCR/DVD Displays n RADIO/TUNER Displays Typical Application T = 25°C, V = 5V, unless otherwise specified. A DD Filament Driver 20021501 FIGURE 1.
