LA7626

Manufacturer Part Number
LA7626
Description
Video chroma and deflection circuit for color TV
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number: EN 2289B
Overview
The LA7625 and LA7626 are based on the LA7620 and
LA7621 with the video circuit DC restoration factor changed
to 100%. The LA7625 and LA7626 are small, multifunction
ICs in which video, chroma and deflection circuits for NTSC
color TV system are packaged in a shrink-type DIP30S (the
same type as the earlier DIP22). In addition to being small,
these ICs greatly reduce the number of components required
and reduce the number of adjustments that must be made. By
combining the LA7625 or LA7626 with the LA7555 or
LA7577 VIF/SIF IC, or LA7832, LA7833, LA7837, or
LA7838 vertical output IC, it is possible to process all
functions of the color television signal system. Note that the
LA7625 has a peak clipping circuit built into the video circuit,
and is suited primarily for compact sets, while the LA7626
does not have a peak clipping circuit and is suited for larger
sets.
