Product Overview
Archer catalog number 276-007 provides a general-purpose 741 operational amplifier in an 8-pin dual in-line package. Custom-packaged for Radio Shack by Tandy Corporation, this analog integrated circuit includes internal frequency compensation, short-circuit protection, and latch-up free performance for prototyping, repair, and analog signal conditioning.
Key Features
- Industry-standard 741 single operational amplifier architecture
- 8-pin dual in-line package (DIP-8) for through-hole mounting or socket installation
- Internal frequency compensation provides circuit stability without external capacitors
- Maximum supply voltage rating of ±18V
- Differential input voltage rating up to ±30V with ±15V input voltage capability
- 500mW maximum power dissipation rating with 85mW power consumption
- Indefinite output short-circuit protection and input overload protection
Applications
- Assembling classic analog audio filters, preamplifiers, and tone circuits on standard perfboards
- Prototyping comparator, summing, and active filter topologies during bench development
- Restoring vintage Radio Shack, Archer, and Tandy electronic kits or test gear
- Building voltage follower and buffer stages on solderless breadboards
Frequently Asked Questions
What is the pinout configuration for this 8-pin DIP 741?
Pin 1 is offset null, pin 2 is inverting input, pin 3 is non-inverting input, pin 4 is negative supply (V-), pin 5 is offset null, pin 6 is output, pin 7 is positive supply (V+), and pin 8 has no connection.
Does this 741 op amp require an external compensation capacitor?
No. Internal frequency compensation is built into the IC, preventing oscillation without requiring external compensation components.
How many operational amplifiers are integrated into this package?
This package contains a single operational amplifier channel.
Decades of breadboard experiments and audio hacks started with this exact card on the Radio Shack pegboard. Plug it into your socket and let the analog circuit do what it was built to do.
