DESCRIPTION This circuit consists of four independent, highgain, internally frequency compensated operation-al amplifiers which were designed specially for au-tomotive and industrial control systems. It oper-ates from a single power supply over a wide rangeof voltages. Operation from split power supplies isalso possible and the low power supply currentdrain is independent of the magnitude of the pow-er supply voltage.

Output Short-circuit to Ground 1)

1. Short-circuit from the output to VCCcan cause excessive heating if VCC > 15V. The maximum output current is approximately 40mA independent ofthe magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers.

Iin Input Current 2)

2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNPtransistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action onthe IC chip. This transistor action can cause the output voltages of the Op-Amps to go to the VCC voltage level (or to ground for a large overdrive)for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.

1. VO = 1.4V, RS = 0, 5V < VCC+ < 30V, 0V < Vic < VCC+ - 1.5V2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so no loading charge

change exists on the input lines3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the

common-mode voltage range is VCC+ 1.5V, but either or both inputs can go to +32V without damage.4. Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typically

can be detected as this type of capacitance increases at higher frequences.
