APPLICATION INFORMATION
NE532 operate with single power supply voltage, true-differential inputs remains linear mode with input common-mode voltage included amps work over wide range power supply voltage with little change performance characteristics. operation possible down minimum supply voltage 2.3V. input common-mode voltage either input signal voltage should allowed negative more than 0.3V.The upper common-mode voltage range VS-15V, either both inputs without damage.
voltage input leads driven negative (V,n -0.3), collector-base junction input transistor becomes forward biased thereby acts.as input diode clamps (max current: 50mA). addition this diode action, there also lateral parasitic transistor action chip. This cause output voltage positive supply voltage level ground large overdrive) time duration that input driven negative. This destructive normal output states will re-establish when input voltage again
returns positive (VIn -0.3V). output stage design 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. 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 junction temperature. Putting direct short-circuit more than amplifier time, total power dissipation will increase destructive levels, properly protected with external dissipation limiting resistors series with output leads amplifiers. larger value output source current which available provides larger output current capability elevated temperatures (see typical performance characteristics) than standard amp.
