QUAD OP AMP AND VOLTAGE REFERENCE

General Description

The AP4303 is a monolithic IC that contains quad

operational amplifiers and a precision shunt regulator,

1.25Vfor AP4303-C or 1.24V for AP4303-D respec-

tively. It is specifically designed to regulate the output

current and voltage levels of switching battery charg-

ers and power supplies.

The four Op Amps feature accurate voltage and current

control. Combining a stable voltage reference with the

four Op Amps makes AP4303 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 AP4303 is available in standard packages of DIP-

16 and SOIC-16.
