AP4303BM-C

Data Sheet 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 respectively. It is specifically designed to regulate the output current and voltage levels of switching battery chargers 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 multifunction 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 corresponding reduction in system complexity and cost. The AP4303 is available in standard packages of DIP16 and SOIC-16.
