Overview
The LA7837, 7838 are vertical deflection output ICs de-
veloped for use in high-grade TVs and displays. The inter-
lace and crossover distortion responses, in particular, have
been greatly improved, allowing excellent picture quality
on large size televisions 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 cir-
cuit. Further, the DC and AC feedback circuit can be formed
with these ICs alone, simplifying pattern design of sets and
ensuring stable performance. All of the functions in a color
TV signal system can be processed by connecting these
ICs with SANYO’s single-chip IC LA7670 series (NTSC)
and LA7680/85 series (PAL/NTSC) (VIF/SIF, video,
chroma, deflection).
The LA7837 has a maximum deflection current of 1.8Ap-
p, making it appropriate for use in portable to mid-size tele-
visions.
The LA7838 has a miximum deflection current of 2.2Ap-
p, so it can be used for large size sets, and can drive from
33 to 37 inches.
