DUAL OP AMP AND VOLTAGE REFERENCE
AP4310
General Description
Features
The AP4310 is a monolithic IC specifically designed Op Amp
to regulate the output current and voltage levels of
switching battery chargers and power supplies.
·
·
Input Offset Voltage: 0.5mV
Supply Current: 75µA per Op Amp at 5.0V Sup-
ply Voltage
The device contains two Op Amps and a 2.5V preci-
sion 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 corre-
sponding reduction in system complexity and cost.
·
·
Unity Gain Bandwidth: 1MHz
Output Voltage Swing: 0 to (V - 1.5) V
CC
·
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 DIP-
8 and SOIC-8.
