If you need more than a +200 gain, try an LM358 in single supply mode and use +5v. These are fantastic op-amps and widely available (Digikey). jm (...) (27 years ago, 27-Aug-97, to lugnet.robotics.handyboard)

If you want to exaggerate the response, perhaps a LM339 +5v single supply comparator will do. Set up your circuit to go high(+5v) above your 2-3v range of operation. This solves all your input problems. Loads of manufactures make this thing. Data (...) (27 years ago, 27-Aug-97, to lugnet.robotics.handyboard)

(...) Assuming you've hooked the LM386's ground to ground and the + voltage to 5v, you should be set hooking the output of the LM386 to the analog input. Do not insert a capacitor in series, as might be shown for hooking up the LM386 to a speaker. (...) (27 years ago, 27-Aug-97, to lugnet.robotics.handyboard)
