Hello Chen, why would you use a unity gain buffer with 3.3V input on +/-15V supplies. Are you expecting gain, do you need a higher 25kHz output waveform than 3.3V input square wave? You would normally use op amp stages perhaps at 5V supply in the early stage and if you need a higher output swing only +/-15V with gain in the last stage.
