Although the ubiquitous LM386 IC was designed ... that determine the amplifier’s gain for audio frequencies, but present a high impedance to RF frequencies so that the circuit might be used as a ...

A regular Hack A Day reader sent in a tip about an LM386 stero amplifier with digital volume control. The resulting build is very professional and could easily be adapted into a slick iPod dock build.

The function of this automatic volume control circuit is to amplify signals without distorting ... It is parallel resistor to R2 and togheter with R3 controls the gain of OP amp A1 (around 20 dB). The ...

multisourced ICs for the core of an inductorless dc-dc converter—the NE555 timer and the LM386 audio amplifier—requires a look at their key specifications and performance in typical circuits.

Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a volume control ... amplifier board complete with sockets to take single or dual op-amp chips. The circuit ...

Simaudio has announced its new MOON 600i V2 integrated amplifier. This muscular-looking ... The 600i features the new M- eVOL2 volume control, which has an incredible 530 steps, allowing for ...

However, another very popular IC, the LM386 audio amplifier, may be a better solution in this application. Note that the results also depend on the specific manufacturer of these multisourced ICs ...
