Application Information
AP358 series amps which operate with only single power supply voltage, have true-differential inputs, remain linear mode with input common-mode voltage VDC. These amplifiers operate over wide range power supply voltage with little change performance characteristics. 25°C amplifier operation possible down minimum supply voltage VDC. Precautions should taken insure that power supply integrated circuit never becomes reversed polarity that unit inadvertently installed backwards test socket unlimited current surge through resulting forward diode within could cause fusing internal conductors result destroyed unit. Large differential input voltages easily accommodated and, input differential voltage protection diodes needed, large input currents result from large differential input voltages. differential input voltage larger than without damaging device. Protection should provided prevent input voltages from going negative more than -0.3 25°C). input clamp diode with resistor input terminal used. reduce power supply current drain, amplifiers have class output stage small signal levels which converts class large signal mode. This allows amplifiers both source sink large output currents. Therefore both external current boost transistors used extend power capability basic amplifiers. output voltage needs raise approximately diode drop above ground bias on-chip vertical transistor output current sinking applications. applications, where load capacitively coupled output amplifier, resistor should used, from output amplifier ground increase class bias current prevent crossover distortion. Where load directly coupled, applications, there crossover distortion. Capacitive loads which applied directly output amplifier reduce loop stability margin. Values 50pF accommodated using worst-case non-inverting unity gain connection. Large closed loop gains resistive isolation should used larger load capacitance must driven amplifier. bias network AP358 establishes drain current which independent magnitude power supply voltage over range VDC. Output short circuits either ground positive power supply should short time duration. Units destroyed, result short circuit current causing metal fusing, rather large increase chip dissipation which will cause eventual failure excessive function temperatures. Putting direct short-circuits more than amplifier time will increase total power dissipation destructive levels, properly protected with external dissipation limiting resistors series with output leads amplifiers. larger value output source current which available 25°C provides larger output current capability elevated temperatures (see typical performance characteristics) than standard amp. circuits presented section typical applications emphasize operation only single power supply voltage. complementary power supplies available, standard circuits used. general, introducing pseudo-ground bias voltage reference will allow operation above below this value single power supply systems. Many application circuits shown which take advantage wide input common-mode voltage range which includes ground. most cases, input biasing required input voltages which range ground easily accommodated.
