The uA747C, uA747M is a dual general-purpose operational amplifier released by Texas Instruments, which features no frequency compensation, low power consumption, short-circuit protection, offset voltage null capability, wide common-mode and differential voltage ranges, and no latch-up.
The uA747C and uA747M are dual general‑purpose operational amplifiers featuring offset‑voltage null capability, low power consumption and short‑circuit protection. Each half is electrically similar to the classic uA741 and is designed for voltage‑follower applications without external frequency compensation.
The document provides absolute maximum ratings, electrical characteristics, typical performance curves, and application information, including temperature ranges (0 °C to 70 °C for uA747C, –55 °C to 125 °C for uA747M) and package options such as D, J, N, W, FK and FLAT PACK.
