Hi all,

Has anyone tried making a VCO using the Harris chip ICL8038 (see
This is a precision waveform generator, allow PWM of sine, triangle
(allows adjustment of slope for previous discussions), and square.
Obviously it'll need other circuitry to change it to be 1V/Oct CV but it
is temperature stable (altiough it does run hot), ie no need to
dismantle any cruise missiles to get the temcos !!! Or find matched
pairs etc etc.

Appreciate any responses, and I've ordered one for testing for my
modular design.
