[sdiy] XR2206 temeperature stability within +/- 5%

[Jean-Pierre Desrochers]

I need a pure sine wave generator adjustable from 10Hz to 60Hz  at around 5v
peak.
The adjusted frequency should stay stable within +/- 5% temperature wise.
The project inside metal enclosure could have temp of up to around +40deg C.
I have a bunch of XR2206 VCO IC on hand to use.
I wonder if the best capacitor to be used here would be
A polystyrene type for temperature stability.. (??)
I'll use 1% metal film resistors for the rest of circuit..
