TDA1170N
LOW-NOISE TV VERTICAL DEFLECTION SYSTEM
. COMPLETE VERTICAL DEFLECTION
SYSTEM
. LOW NOISE
. SUITABLE FOR HIGH DEFINITION
MONITORS
DESCRIPTION
The TDA1170N is a monolithic integrated circuit in
a 12-lead quad in-line plastic package. It is in-
tended for use in black and white and colour TV
receivers. Low-noise makes this device particularly
suitable for use in monitors. The functions incorpo-
rated are : synchronization circuit, oscillator and
ramp generator, high power gain amplifier, flyback
generator, voltage regulator.
