Data Sheet
QUAD OP AMP AND VOLTAGE REFERENCE
General Description
The AP4302 is a monolithic IC specifically designed
to regulate the output current and voltage levels of
switching battery chargers and power supplies.
The device contains quad Op Amps and a 2.5V exter-
nally adjusted voltage reference in a 16-pin package.
The four Op Amps feature accurate voltage and current
control. Combining a stable voltage reference with the
four Op Amps makes AP4302 ideal for use in multi-
function charger, power supply voltage monitor, signal
processing and control system.
The IC offers the power converter designer a control
solution that features increased precision with a corre-
sponding reduction in system complexity and cost.
The AP4302 is available in standard packages of DIP-
16 and SOIC-16.
