GENERAL DESCRIPTION

The MP7652 is ideal for digital gain control of high frequency

analog signals such as video, composite video, CCD and oth-

ers. The device includes 4-channels of high speed, wide

bandwidth, two quadrant multiplying, 8-bit accurate digital-to-

analog converter. It includes an output drive buffer per channel

capable of driving a +1mA (typ) load. 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 tech-

nology.

small signal bandwidth from V_REFto output up to 15 MHz (typ),

fast output settling time of 150 ns, and excellent V_REF

feedthroughisolation. The bottom of each DAC reference string

is brought out separately for totally isolated operation. In addi-

tion, low distortion in the order of 0.25% with a 1 V p-p, 1 MHz

signal is achieved.

The combination of a constant input Z and the ability to vary

V_REFNwithin V_CC–1.8 and V_EE+1.5 V allows flexibility for opti-

mum system design.

The MP7652 is fabricated on a junction isolated, high speed

BiCMOS (BiCMOS IV^TM) process with thin film resistors. 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
