DESCRIPTION This circuit consists independent, high gain, internally frequency compensated which were designed specifically operate from single power supply over wide range voltages. power supply drain independent magnitude power supply voltage. Application areas include transducer amplifiers, gain blocks conventionalop-amp circuits which more easilyimplemented single power supply systems. example, these circuits canbe directly operatedoff standard+ power supply voltage which used logic systems will easily provide required interface electronics without requiring additional power supply. linear mode input common-mode voltage range includes ground output voltage also swing ground, even though operated from only single power supply voltage. gain-bandwidth product temperature compensated.

This input current only exist when voltage input leads driven negative. collector-base junction input transistor becoming forward biased thereby acting input diode clamps. addition this diode action, there also parasitic action chip. This transistor action cause output voltages Op-amps voltage level ground large overdrive) time duration that input driven negative. This destructive normal output will again input voltage higher than -0.3V.
