Texas Instruments TEXAS INSTRUMENTS uA747C, uA747M DUAL GENERAL-PURPOSE OPERATIONAL AMPLIFIERS datasheet manual specifications guide user's handbook
Summary
The uA747 series is a versatile dual general-purpose operational amplifier designed for reliable signal amplification in diverse circuitry. Featuring low power consumption, inbuilt offset null capability, and short-circuit protection, it maintains stability without external frequency compensation components. This manual provides comprehensive technical specifications, electrical characteristics, and absolute maximum ratings for both C (0°C to 70°C) and military grade M (-55°C to 125°C) variants. Ideal for engineers developing stable voltage-follower applications requiring high performance across a wide temperature range.

description
u A747m FK PACKAGE (TOP VIEW)
The u A747 is a dual general-purpose operational amplifier featuring offset-voltage null capability. Each half is electrically similar to u A741. The high common-mode input voltage range and the absence of latch-up make this amplifier ideal for voltage-follower applications. The device is
short-circuit protected and the internal frequency OUT

compensation ensures stability without external NC
components. A low-value potentiometer may be NC
connected between the offset null inputs to null out NC
