General Description
AMS682 General Description
The AMS682 is a CMOS charge pump converter that provides an inverted doubled output from a single positive supply.
Requiring only three external capacitors for full circuit implementation the device has an on -board 12kHz (typical) scillator which provides the clock.
Low output source impedance (typically 140W), provides output current up to 10mA. The AMS682 features low uiescent current and high efficiency, making it the ideal choice for a wide variety of applications that require a negative voltage derived from a single positive supply. The compact size and minimum external parts count of the MS682 makes it useful in many medium current, dual voltage analog power supplies.
The AMS682E is operational in the full industrial temperature range of -40°C to 85°C while AMS682C is operating over a 0°C to 70°C temperature range. The AMS682E/AMS682C are available in surface mount 8-Pin SOIC (SO-8) and 8-Pin Plastic DIP (PDIP) packages.
