NTE7039 & NTE7104
Integrated Circuit
Vertical Deflection Output Circuit
w
/Drive Circuit for CRT Display
Description:
The NTE7039 and NTE7104 are vertical deflection output ICs developed for use in high–grade TVs
and displays. The interlace and crossover distortion responses, in particular, have been greatly im-
proved, allowing excellent picture quality on large size television screens and high precision interlace
mode displays.
Also, pulse signals can be used for input signals due to the on–chip sawtooth wave generating circuit
and driver circuit. Further, the DC and AC feedback circuits can be formed with these ICs alone, sim-
plyfing pattern design of sets and ensuring stable performance.
The NTE7104 has a maximum deflection current of 1.8A
p–p
, making it appropriate for use in portable
to mid–size televisions while the NTE7039 has a minimum deflection current of 2.2A
p–p
, so it can be
used for larger size sets, and can drive television screen sizes from 33 to 37 inches.
