QUAD OP AMP AND VOLTAGE REFERENCE
AP4302
General Description
Features
The AP4302 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 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.
·
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 Voltage Reference: 2.5V
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.
