Tindie Weblog | DIP-8 Op-Amp for Prototyping!

Once I noticed this itemizing, I couldn’t assist however suppose “What a cool thought!”. An inverting audio amplifier with potentiometer adjustment in a DIP-8 ready-to-breadboard bundle! This could be so useful when prototyping any audio-related initiatives. It doesn’t matter what, you appear to all the time want some acquire alongside the way in which, and with the ability to simply plug in a ready-made resolution will save breadboard house and prototyping time.

By putting all of the elements in the identical footprint as a DIP-8 op-amp, you get all of the performance with out having to calculate and add all of the exterior elements essential. Delivering anyplace from +/-20dB of acquire (sure, it will possibly attenuate in addition to amplify!), this inverting op-amp is ideal when used as a ultimate amplifying stage, as a pre-amp driving another circuitry, and even simply as inter-stage acquire steps between successive results.

It does require a bipolar provide. A easy method to get a really clear, steady bipolar provide is to make use of two 9V batteries, with the unfavourable terminal of 1 related to the optimistic terminal of the opposite. This works as your “floor” or reference voltage, after which you’re left with exceptionally noise-free +/-9V provides for op-amps and different circuitry (because of Ben Krasnow for this tip!).

The documentation may be very clear and well-designed, with easy-to-read schematics and pinouts. The included op-amp isn’t specified but it surely’s seemingly one thing alongside the strains of a TL081 or the same high-quality audio op-amp. Having building-block components like this in your drawer could make prototyping and testing a lot less complicated, and understanding that it simply works can scale back complications when one thing does go improper!
