Hey All
I am reading the datasheet for a KA3844B, after the main table of values and tolerances in a small section on page 4 it gives
(VCC=15V, RT=10KΩ, CT=3.3nF, TA= 0°C to +70°C unless otherwise specified)
what i would like to know is what RT refers to? Is this the resistance seen from Vcc to Gnd?

Datasheet here: http://www.fairchildsemi.com/ds/KA/KA3844B.pdf

cheers!

 

Resistor Timing like Capacitor Timing connected to pin 4 sets up the RC time constant for the oscillator.

 

R total is my guess it is on the schematic bellow the table.

 

See page 6 for connection info and equations.
