Note 2: All devices are 100% production tested at T

A

= +25°C. Specifications over temperature are guaranteed by design.

Note 3: The clamp voltage at the input is V

.

Note 4: The key-clamp voltage is above the sync-tip clamp voltage by approximately 0.7V, and is adjusted by varying R

KEYREF

.

Note 5: Measured at f = 100Hz at thermal equilibrium.
