DUAL OP AMP AND VOLTAGE REFERENCE
AP4300
General Description
Features
The AP4300 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: 250µA per Op Amp at 5.0V Sup-
ply Voltage
The device contains two operational amplifiers and a
precision shunt regulator. Op Amp 1 is designed for
voltage control, whose 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 18V
Voltage Reference
·
Fixed Output Voltage Reference: 2.5V, 2.6V
Voltage Tolerance: 0.5%, 1%
Sink Current Capability from 0.1 to 80mA
·
·
The AP4300 is available in standard packages of DIP-
8 and SOIC-8.
