Description
The LM101A is a general purpose operational amplifier which offers many features: supply voltages from ±5V to ±22V, low current drain, overload protection on the input and output, no latch-up when the common-mode range is exceeded, free from oscillations and compensation with a single 30pF capacitor. It has advantages over internally compensated amplifiers in that the compensation can be tailored to the particular application: slew rate of 10V/µs and bandwidth of 3.5MHz can be easily achieved.

LM301AN FAQ
What is a single op amp?
A single-supply op amp is specifically designed to have a common-mode range which extends all the way to the negative supply (ground). Also, its output stage is usu- ally designed to swing close to ground.
What is OPM amplifier?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
What are the types of operational amplifier?
Op amps can be classified into 3 main types based on the input/output voltage range: Dual Supply, Single Supply, and Rail-to-Rail. The input/output voltage range of each type of op amp is shown below.
What is compensated op amp?
Compensated op amps, or simply op amps, are traditionally designed to be stable for gains down to and including unity gain. Decompensated, or less compensated op amps, exhibit higher bandwidth and slew rate than op amps compensated for unity gain.
Where are operational amplifiers used?
741 Operational Amplifiers (also known as Op Amps) are used in a range of circuits. They are generally used to amplify weak electrical current in a circuit. Radios, stereo systems, headphones, TVs and many other electrical products include an operational amplifier as a component in many of their circuits.
