Description
General part information
ADM8828 Series
The ADM8828/ADM8829 is a charge-pump voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative –1.5 V to –5.5 V output supply. This inverting scheme is ideal for generating a negative rail in single power-supply systems. Only two small external capacitors are needed for the charge pump. Output currents up to 25 mA with greater than 99% efficiency are achievable.The ADM8828 also features a low power shutdown (SHDN) pin. This can be used to disable the device and reduce the quiescent current to 20 nA.The ADM8828/ADM8829 is available in a 6-lead SOT-23 package.ApplicationsHandheld InstrumentsLCD PanelsCellular PhonesPDAsRemote Data AcquisitionOp Amp Power Supplies
