Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking ...

What I’d stumbled upon was a chopper amplifier, a slightly ungainly and long superseded solution to the problem of DC amplification from the days before ubiquitous integrated circuit op-amps.

This is not always the case with all types of amplifiers. It may be desirable to have the transistor conducting for only a portion of the input signal The portion of the input for which there is an ...

meter. In partnership with Purifi, Marantz has developed a new amplifier, two of which are used for dual-mono operation. The MODEL 10 operates as a fully balanced amplifier from input to output.
