General Description
The MAX9657 is a small, low-power, quad video ampli-
fier with input sync-tip clamps. It features a bandwidth
of 15MHz, making it suitable for not only standard-defi-
nition video signals, but also video graphics array
(VGA) signals with a 640 x 480 resolution at up to 85Hz
refresh rate.
The MAX9658 is a quad video amplifier with integrated
lowpass filters and input sync-tip clamps. The lowpass
filters typically have ±1dB passband flatness out to
9.5MHz and 47dB attenuation at 27MHz. Specially suit-
ed for composite video signals, the MAX9658 is ideal
for performing anti-alias filtering at the inputs of a digital
video recorder or for performing reconstruction filtering
at the outputs of a SCART set-top box.
Both devices require that the incoming video signals be
AC-coupled to the inputs. The input sync-tip clamps set
the internal DC level of the video signals.
The amplifiers have 2V/V gain, and the outputs can be
DC-coupled to a 75
Ω load, which is the equivalent of
two video loads, or AC-coupled to a 150
Ω load.
Both the MAX9657/MAX9658 feature a low-power shut-
down mode, in which supply current is reduced to
35A.
The MAX9657/MAX9658 operate from a single 2.7V to
3.6V supply, are specified over the -40°C to +125°C
automotive temperature range, and are offered in a
small, 16-pin QSOP package.
