AC Electrical Characteristics
(VCC = +5V, GND = 0V, RL = 150Ω to GND, VDISABLE = +5V, RKEYREF = 6kΩ, CIN = 0.1µF, TA = TMIN to TMAX, unless otherwise noted.
Typical values are at TA = +25°C.)

Note 2: All devices are 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 3: The clamp voltage at the input is VCLAMP (measured at the output) divided by gain + VBE.
Note 4: The key-clamp voltage is above the sync-tip clamp voltage by approximately 0.7V, and is adjusted by varying RKEYREF.
Note 5: Measured at f = 100Hz at thermal equilibrium.
