Product Overview
The National Semiconductor LM301AH is a classic general-purpose operational amplifier housed in an 8-lead TO-99 hermetic metal can. Designed as an improved direct replacement for the LM101A series in commercial temperature ranges, the LM301A architecture provides low input bias currents and short-circuit protection across wide supply rails. Because it is externally compensated, circuit designers can tailor frequency response and slew rate to custom audio, instrumentation, or active filtering stages.
Key Features
- 8-lead TO-99 (H08C) hermetic metal can package
- Translucent bottom insulating spacer ring included on leads
- Wide operating voltage range: 10V to 36V single supply, ±5V to ±18V dual supply
- Low supply current drain: 1.8 mA typical
- Input bias current: 70 nA typical, 250 nA maximum
- Gain bandwidth product: 1 MHz
- Slew rate: 0.5 V/µs
- Externally compensable for tailoring stability and speed
Applications
- Bench restoration of vintage 1970s and 1980s analog test instruments, synthesizers, and studio gear
- Precision summing amplifiers, active low-pass filters, and voltage followers in maker lab builds
- Direct replacement maintenance on legacy industrial control and sensor interface cards
Frequently Asked Questions
What package style is this LM301AH op amp?
It is in an 8-lead circular TO-99 metal can with radial leads, featuring an installed plastic standoff spacer on the base.
What operating temperature range does the LM301AH support?
The LM301AH is rated for the commercial temperature operating range of 0°C to +70°C.
Why choose a single verified piece over an uninspected surplus lot?
Chasing bulk lots often leaves you with mixed variants, bent pins, or unknown wear. This listing delivers the exact metal-can unit shown in the photographs, with intact markings and straight leads ready for your repair. Shipping is $8 flat rate, free once your order passes $28, and orders ship out from our Idaho warehouse the same or next business day.
Vintage metal cans carry a presence that plastic DIPs can never match, bringing authentic silicon stability back to the workbench for your next analog restoration.
