BCD AP4310P Dual op amp and voltage reference Datasheet

Preliminary Datasheet
DUAL OP AMP AND VOLTAGE REFERENCE
AP4310
General Description
Features
The AP4310 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: 75µA 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 Op Amps and a 2.5V precision shunt voltage reference. Op Amp 1 is designed for
voltage control with its 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 36V
Voltage Reference
· Fixed Output Voltage Reference: 2.5V
· Voltage Tolerance: ± 0.4%, ± 1%
· Sink Current Capability: 0.05 to 80mA
· Typical Output Impedance: 0.2Ω
The AP4310 is available in standard packages of DIP8 and SOIC-8.
