Product Information

Philips Semiconductors Linear Products Product specification Dual operational amplifier µA747C 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. PIN CONFIGURATION N Package INV.
