Monolithic Linear IC

LA7625

Video, Chroma and Deflection Circuit for Color

Television Sets

Overview

The LA7625 is based on the LA7620 with the video circuit DC restoration factor changed to 100%. The LA7625 is 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 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.
