Linear - Amplifiers - Instrumentation 
Instrumentation amplifiers, or instrumentation OP Amps, are specialized types of operational amplifiers that are used to provide a high input impedance, low output impedance, and good gain accuracy over a wide range of frequencies. In general, the most common instrumentation OP Amp are the single-ended, three-stage type, with the additional stages providing higher gain accuracy, bias stability and input impedance. Instrumentation amplifiers are used to accurately measure and monitor signals in a wide variety of applications, such as medical, industrial, automotive and audio/video equipment. The main advantages of instrumentation OP Amps include their wide bandwidth, low noise, high input impedance, and excellent stability.

Buffer Amps 
Buffer amplifiers, or buffer OP Amps, are specialized types of operational amplifiers that provide low noise, high input impedance, low output capacitance, and excellent stability. Buffer amplifiers are typically used in systems where a high input impedance is desired to eliminate signal loading, while the high output impedance allows the amplifier to drive difficult loads without distortion. The most common buffer OP Amps are the single-ended unity-gain type, with higher gain types also available. Buffer amplifiers are ideal for providing a high input impedance to medium-power applications such as radio receivers, audio amplifiers and oscilloscopes.
