_______________Detailed Desc ription
The MAX496/MAX497 are quad, high-speed, closed-loop
voltage-feedback video amplifiers with fixed gain settings
of +1 and +2, respectively (Figure 1). These amplifiers
use a unique two-stage voltage-feedback architecture
that combines the benefits of conventional voltage-feed-
back and current-mode-feedback topologies. They
achieve wide bandwidths and high slew rates while main-
taining precision. A resistively loaded first stage provides
low input-referred noise even with low supply currents of
8mA per amplifier. The above features, along with the
ability to drive 50
or 75
back-terminated cables to
±2.8V and low differential phase and gain errors, make
these amplifiers ideal for the most demanding component
and composite video applications.
__________Applic ations Information
The feedback elements of the MAX496/MAX497 are
included internally in the device to set the closed-loop
gain to A
V
= +1 and A
V
= +2, respectively. Closing the
loop internally on the chip minimizes problems associ-
ated with the board and package parasitics influencing
the amplifier’s frequency response.
