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.
An open loop architecture (patent pending) provides wide
small signal bandwidth from V
REF
to output up to 15 MHz (typ),
fast output settling time of 150 ns, and excellent V
REF
feedthrough isolation. 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
REFN
within 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.
