GENERAL DESCRIPTION

The MP7651 is ideal for direct gain control of video, compos-

ite video, CCDandotherhighfrequencyanalogsignals. Thede-

vice includes 8-channels of high speed, high bandwidth, two

quadrant, multiplying, 8-bit accurate digital-to-analog converter.

It includes an output drive buffer per channel capable of driving

+1mA (typ) to a load. DNL of better than +0.8 LSB is achieved

with a channel-to-channel matching of better than 0.5%. Stabil-

ity, matching, and precision of the DACs is achieved by using

EXAR’sthinfilmtechnology. Also, excellentchannel-to-channel

isolation is achieved with EXAR’s BiCMOS process which can-

not be achieved using a typical CMOS technology.

fast output settling time, and V_REFfeedthrough isolation of

–65dB or better. In addition, low distortion in the order of 0.25%

with a 1 V p–p, 1 MHz signal.

A specified and constant input impedance of each V_REF+in-

put gives flexibility for optimal system design. The serial data

3-wire standard µ-processor logic interface reduces pin count,

package size (28 pin), and board wire (space). Additionally, the

internal chip select decoder allows for easy daisy chaining with-

out the addition of separate control logic.

MP7651 is fabricated on a junction isolated, high speed, dual

metal,linearcompatibleBiCMOS(BiCMOSIV^TM)thinfilmresis-

tors. This process enables precision high speed analog/digital

(mixed-mode) circuits to be fabricated on the same chip.

An open loop architecture (patent pending) provides wide

small signal bandwidth from V_REFto output up to 10 MHz (typ),
