Just ordering the parts - which ceramic caps would you use? (Cement Coated
TXFN/HXFY/HXFZ Series Disc Ceramic Capacitors OK?)



Ta,



Paul.

Not quite, they are dual op-amps so will do two circuits.

Single Op Amp

nc      1      8      nc
-in      2      7      +ve
+in      3      6      out
-ve      4      5      nc

Dual op amp

out1      1      8      +ve
-in1      2      7      out2
+in1      3      6      -in2
-ve      4      5      +in2

Make sure you fit a 0.1uF ceramic capacitor from each power supply pin ( 4
&
8) to ground as close as possible to the opamp
