Data Sheet QUAD OP AMP AND VOLTAGE REFERENCE AP4303 General Description Features 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. 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 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. 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: 0.2Ω · Externally Adjusted Output Voltage Reference: 1.25V for AP4303-C and 1.24V for AP4303-D 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. Applications · · Battery Charger Switching Power Supply DIP-16 SOIC-16 Figure 1.
