LM301AN Operational Amplifier DIP-8
The LM301AN is a classic, single-package operational amplifier offered in an 8-pin DIP (DIP-8) that serves as a flexible building block for analogue designs. It’s built for general-purpose amplification across a wide supply range (±5 V to ±22 V), and was designed so the external compensation capacitor can be tailored to the application. This means designers can optimize stability, bandwidth and slew response for a given circuit instead of relying on fixed internal compensation.
In normal operation the LM301AN performs as a low-drift, low-noise amplifier with modest input currents and millivolt-level offset. It provides useful open-loop gain, predictable common-mode behavior and protection against overloads on the input and output so that it remains robust in many bench and field circuits. The device can be used as a voltage follower, small-signal amplifier, or as the active element in filters and integrators.
Mechanically the LM301AN is supplied in a standard plastic DIP-8 footprint with the pinout and package dimensions suitable for through-hole prototyping and legacy PCBs. Its external compensation (single 30 pF shown in datasheet examples) and tolerant input range let engineers trade off slew rate, bandwidth and stability to meet application needs. The LM301AN remains a simple, adaptable op-amp for educational, hobbyist and many industrial uses.
Features:
- Single, general-purpose operational amplifier in DIP-8.
- External compensation (single 30 pF) allows tailoring of stability and bandwidth.
- Wide supply range: ±5 V to ±22 V.
- Low input offset and low input bias current (millivolt / nanoamp class).
- Built-in protections: overload protection on input and output; no latch-up when common-mode range is exceeded.
- Can achieve higher slew performance when used in inverting configuration (see datasheet note).
