Hi All, I'm try to use LM380 to drive a load but encountered some problems. The circuit is a very standard one with a capacitor in the input and a capacitor in the output to block the dc, I used a function generator to apply a sinewave to the input, but found that the output would very easily get clipped (unless the input signal is very very low in amplitude). the maximum p-p amplitude of the output signal is 4 volts while my Vs is at 12V dc. I tried all frequencies from 20Hz to 1KHz, the result is the same. Is there any way I can get an output sinewave without clipping for higher than 4 volt p-p, preferablly close to the supply voltage (i.e. 12V)? Thanks in advance!
