DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC358 LOW POWER DUAL OPERATIONAL AMPLIFIERS DESCRIPTION The µPC358 is a dual operational amplifier which is designed to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the power supply current drain is very low. Further advantage, the input commonmode voltage range includes ground in the linear mode. FEATURES • Internally frequency compensation • Wide output voltage swing V– to V+ –1.5 V • Common mode input voltage range includes V– • Wide supply voltage range 3 V to 30 V (Single) ± 1.5 V to ± 15 V (Split) • Output short circuit protection EQUIVALENT CIRCUIT (1/2 Circuit) 100 µ A Q5 Q2 II Q1 Q3 Q4 Q6 CC Q7 RSC OUT IN Q10 Q8 Q [ ... ]
