TYPICAL APPLICATION
The TEA5101B consists of three independent am-
plifiers. Each of them includes :
- A differential amplifier, the gain of which is fixed
by external feedback resistors,
- A voltage reference,
- A PMOS transistor providing a copy of the cath-
ode current,
- A protection diode against CRT arc discharges.
