LOW-NOISE VERTICAL DEFLECTION SYSTEM

FEATURES SUMMARY

■ COMPLETE VERTICAL DEFLECTION

SYSTEM

■ LOW NOISE

■ SUITABLE FOR HIGH DEFINITION

MONITORS

■ ESD PROTECTED

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.
