Manufacturer: Description:Finally, trimming the various pins for lowest distortion deserves some attention. With pins 7 and 8 connected together and the pot at pin 7 and 8 externally set at its maxi- mum, adjust the ratio of RA and RB for 50% duty cycle. Then adjust a pot on pin 12 or both pins 1 and 12 depending on minimum distortion desired. After these trims have been made, set the voltage on pin 8 for the lowest frequency of interest. The principle error here is due to the excess current of Q7 causing a shift in the duty cycle. This can be partially compensated for by bleeding a small current away from pin 5. The simplest way to do this is to connect a high value of resistance (10MΩ to 20MΩ) from pin 5 to V- to bring the duty cycle back to 50%. This should result in a reasonable com- promise between low distortion and large sweep range. |
