TEA2037A
Line Output (pin 14)
It is an open collector output which is able to drive
pulse current of 800mA for a rapid discharging of
the darlington base. The output pulse time is 22µs
for a 64µs period.
The oscillator thresholds are internally fixed by re-
sistors. The oscillator is synchronized during the
last half free run period. The input current during
the charge of the capacitor is less than 100nA.
Frame Output Amplifier
This amplifier is able to drive directly the frame
yoke. Its output is short circuit and overload pro-
tected; it contains also a thermal protection.
