UA741 / LM741 DIP-8 General Purpose Operational Amplifier IC (10-Pack)
The UA741 (also known as LM741) is the classic single general-purpose operational amplifier in a DIP-8 through-hole package. With a 1MHz gain-bandwidth product and internal frequency compensation, it requires no external compensation capacitors and is the foundational op-amp for learning analog circuit design, comparators, integrators, and signal conditioning.

- Electronics education and lab exercises
FAQ
Q: Can UA741 operate on a single supply? No - UA741 requires a dual supply (+/-5V to +/-18V). For single-supply operation, use LM358 or TL072 which include ground in their common-mode input range.
Q: Why is UA741 slew rate so low (0.5V/us)? The internal 30pF compensation capacitor limits slew rate. This makes UA741 unsuitable for audio above ~10kHz or fast signal processing. Use TL072 or NE5532 for audio applications.
