FIGURE 24. OUTPUT SWING vs FREQUENCY (NOTE)

FIGURE 25. OUTPUT SWING vs FREQUENCY (NOTE)

NOTE:

This curve was obtained by noting the output voltage necessary to produce an observable distortion for a given frequency. If higher distortion is

acceptable, then a higher output voltage for a given frequency can be obtained. However, operating the HA-5033 with increased distortion (to the

right of curve shown), will also be accompanied by an increase in supply current. The resulting increase in chip temperature must be considered

and heat sinking will be necessary to prevent thermal runaway. This characteristic is the result of the output transistor operation. If the signal amplitude

or signal frequency or both are increased beyond the curve shown, the NPN, PNP output transistors will approach a condition of being simultaneously on.

Under this condition, thermal runaway can occur.
