Vary stable chip (I haven't accidentally fried even 1 of them). I have not been able to test the frequency sweep function due to some issues with my bench PSU. Using the test circuits presented in the datasheet I was able to produce sine, triangle and square waves.

|Formula for determining resistor and capacitor values|
Current ranges at pins 4 and 5 are set by the resistor values Ra and Rb and need to fall within the range of 0.01mA to 1mA (so resistor values depend on supply voltage - I'm using 12v so my range is 2.6k to 260k).
