| 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 externally 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 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 AP4302 is available in standard packages of DIP16 and SOIC-16. AP4302 Features Op Amp * Input Offset Voltage: 0.5mV * Supply Current: 250A per Op Amp at 5.0V Supply Voltage * Unity Gain Bandwidth: 1MHz * Output Voltage Swing: 0 to (VCC-1.5)V * Power Supply Range: 3 to 18V Voltage Reference * Reference Voltage Tolerance: 0.5%, 1% * Sink Current Capability from 0.1 to 80mA * Output Dynamic Impedance: 0.2 * Externally Adjusted Voltage Reference: 2.5V Applications * * * Battery Charger Switching Power Supply Mother Board SOIC-16 DIP-16 Figure 1.
