Exar Corporation MP7652
The MP7652 is ideal for digital gain control of high frequency analog signals such as video, composite video, CCD and others. The device includes 4-channels of high speed, wide bandwidth, two quadrant multiplying, 8-bit accurate digital-toanalog converter. It includes an output drive buffer per channel capable of driving a +1mA (typ) load.FEATURES

GENERAL DESCRIPTION
DNL of better than +0.5 LSB is achieved with a channel-to-channel matching of typically 0.5%. Stability, matching, and precision of the DACs are achieved by using MPS’ thin film technology. Also, excellent channel-to-channel isolation is achieved with EXAR’s BiCMOS process which cannot be achieved using a typical CMOS technology.
