MITSUBISHI ICs (Monitor) M52734SP 3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING DESCRIPTION The M52734SP is a semiconductor integrated circuit amplifies video signals, having a 3-channel amplifier with a band width of 130MHz. The circuit also features the OSD mixing function. The circuit is most useful with high resolution displays that have OSD, and its function are available for each channel, including OSD blanking, OSD mixing, wide-band amplification, contrast control (main and sub), and brig.

To adjust contrast, two types of controls are provided, main and sub. With the main control, the contrast of the 3-channels can be changed simultaneously. Sub controls are used to adjust the contrast of a given channel individually. The control terminals can be controlled by applying a voltage of 0 to 5V. The DC power remains stable at the IC output terminal because a feedback circuit is built in.
