Data Sheet DUAL OP AMP AND VOLTAGE REFERENCE AP4300 General Description Features The AP4300 is a monolithic IC specifically designed to regulate the output current and voltage levels of switching battery chargers and power supplies. Op Amp · Input Offset Voltage: 0.5mV · Supply Current: 250µA per Op Amp at 5.0V Supply Voltage · Unity Gain Bandwidth: 1MHz · Output Voltage Swing: 0 to (VCC - 1.5) V The device contains two operational amplifiers and a precision shunt regulator. Op Amp 1 is designed for voltage control, whose non-inverting input internally connects to the output of the shunt regulator. Op Amp 2 is for current control with both inputs uncommitted. The IC offers the power converter designer a control solution that features increased precision with a corresponding reduction in system complexity and cost. · Power Supply Range: 3 to 18V Voltage Reference · Fixed Output Voltage Reference: 2.5V, 2.6V · Voltage Tolerance: 0.5%, 1% · Sink Current Capability from 0.1 to 80mA The AP4300 is available in standard packages of DIP8 and SOIC-8.
