DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC324 LOW POWER QUAD OPERATIONAL AMPLIFIER DESCRIPTION The µPC324 is a quad 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 can also swing to ground in the linear mode. FEATURES • Internal frequency compensation • Wide output voltage swing V– to V+–1.5 V • Common Mode input voltage range includes V– • Wide supply range 3 V to 30 V (Single) ± 1.5 V to ± 15 V (Split) • Output short circuit protection EQUIVALENT CIRCUIT (1/4 Circuit) 100 µ A 6 µA Q2 Q3 6 µA Q5 II IN Q10 Q8 Q9 Q12 50 µA V– Q1 [ ... ]
