LM9022 is Vacuum Fluorescent Display Filament Driver manufactured by National Semiconductor.
| Part Number | Description |
|---|---|
| LM90 | Remote Diode and Local Digital Temperature Sensor |
| LM9011 | Electronic Ignition Interface |
| LM903 | Fluid Level Detector |
| LM9036 | Ultra-Low Quiescent Current Voltage Regulator |
| LM9040 | Dual Lambda Sensor Interface Amplifier |
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.
