Not quite what I was on about. If you check the 3232 data sheet you will find
that different caps are specified for single voltage working, and variable
voltage working. For variable voltage one cap is 0.1uF min, and the other three
are 0.47uF min. For operating at fixed 3 Volt, all caps are 0.1uF min. For 5
volt fixed supply, one cap is 0.047uF minimum, and the other three are 0.33uF
min. Go figure - but the way I read the data sheet, it only guarantees to swing
the output +/-6 Volts.
