DESCRIPTION
The TDA1175P is a monolithic integrated circuit in
POWERDIP16 plastic package. It is intended for
use in black and white and colour TV receivers.
Low-noise makes this device particularly suitable
for use in monitors.
The functions incorporated are : synchronization
circuit, oscillator and ramp generator, high power
gain amplifier, flyback generator, voltage regulator.
