Question

What is precision amplifier?

Answer 1

precision amplifier is give sinosodialwave form.

Answer 2

It's a operational amplifier that has had the components trimmed with lasers to optimize the characteristics.

Answer 3

Generally, an amplifier is any device that changes, usually increases, the amplitude of a signal. The "signal" is usually voltage or current.

In popular use, the term today usually refers to an electronic amplifier, often as in audio applications. The relationship of the input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain. A related device that emphasizes conversion of signals of one type to another (for example, a light signal in photons to a DC signal in amperes) is a transducer, or a sensor. However, a transducer does not amplify power
