1 / 5 page Philips Semiconductors Linear Products Product specification µA747C Dual operational amplifier 54 August 31, 1994 853-0899 13721 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 µA741 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 PIN CONFIGURATION + B A – INVERTING INPUT B NON–INVERTING INPUT B OFFSET NULL B V– OFFSET NULL A NON–INVERTING INPUT A INV.
