6. Philips Semiconductors Linear Products Dual operational amplifier DESCRIPTION The 747 is a pair of high performance monolithic operational amplifiers constructed on a single silicon chip High common mode voltage range and absence of latch up make the 747 ideal for use as a voltage follower The high gain and wide range of operating voltage provides superior performance in integrator summing amplifier and general feedback applications The 747 is short circuit protected and requires no external components for frequency compensation The internal 6dB octave roll off insures stability in closed loop applications For single amplifier performance see uA741 data sheet FEATURES No frequency compensation required Short circuit protection Offset voltage null capability Large common mode and differential voltage ranges Low power consumption No latch up ORDERING INFORMATION DESCRIPTION 14 Pin Plastic DIP EQUIVALENT SCHEMATIC PIN CONFIGURATION Product specification uA747C INV INPUT A NON INVERTING INPUT A OFFSET NULL A v OFFSET NULL B NON INVERTING INPUT B INVERTING INPUT B N Package TOP VIEW OFFSET NULL A V A OUTPUT A NO CONNECT OUTPUT B V B OFFSET NULL B TEMPERATURE RANGE ORDERCODE DWG 0 C to 70 C wA747CN 0405B INVERTING INPUT s o V a8 NON INVERTING INPUT oK D e e E e 30pF 452 lis apj
