DESCRIPTION
These circuits consist of four independent, high gain, internally frequencycompensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
All the pins are protected against electrostatic discharges up to 2000V (as a consequence, the input
voltages must not exceed the magnitude of VCC+ or VCC-.)

Notes : 1. Short -circui t s f rom t he out put t o VC C can cause excessi ve heat i ng if VC C > 15V. T he maxi mum out put current is approxi mat el y 40mA i ndependent of the magni t ude of VC C. Destructi ve di ssipat i on can res ult f rom simul taneous short -circuit on al l ampli f iers.
2.The di rect ion of the i nput current is out of t he IC. Thi s current is essenti al l y constant, i ndependent of the st ate of the out put so no l oadi ng change exists on the i nput l i nes.
3.Vo = 1. 4V , Rs = 0Ω, 5V < V CC + < 30V , 0 < Vic < V C C+ - 1.5V
4.The i nput common-mode vol t age of eit her i nput si gnal volt age shoul d not be allowed to go negat i ve by more than 0.3V . T he upper end of the common-mode vol tage range i s VC C+ - 1.5V , but eit her or bot h i nput s can go
to +32V wi thout damage.
5. Due t o the proxi mit y of ex ternal component s insure t hat coupl ing i s not ori gi nat ing vi a stray capaci t ance between these ext ernal part s. T hi s t ypi call y can be detect ed as t his t ype of capaci tance i ncreases at higher f requences.
6. This input current onl y exi sts when t he volt age at any of t he i nput leads is driven negat ive. It i s due t o t he coll ect or-base juncti on of t he i nput PNP transistor becomi ng forward biased and thereby act ing as input diodes clamps. I n addit i on to thi s di ode act i on, there i s al so NPN parasit i c act ion on the I C chip. t hi s t ransi st or acti on can cause t he output vol t ages of the Op-amps t o go t o the VCC volt age l evel (or to ground f or a l arge overdri ve) f or t he ti me durat ion t han an input i s driven negati ve.
