Product specification

Dual operational amplifier

µA747C

DESCRIPTION

PIN CONFIGURATION

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.
