_______________General Desc ription
The MAX498/MAX499 are high-speed, quad/triple, sin-
gle-pole/double-throw video switches with on-board
closed-loop buffer amplifiers. The buffer amplifiers fea-
ture +6dB gain (A
VCL
= 2V/V), 250MHz -3dB band-
width, 70MHz 0.1dB gain flatness, and 1250V/
μ
s slew
rate. Fast switching time (3ns) and fast settling time
(12ns for a 4V step) make these devices excellent
choices for a wide variety of video applications. The low
differential gain/phase errors (0.03%/0.06°) and wide
bandwidth make them ideal for both composite-video
and RGB applications. The amplifiers are capable of
delivering ±2.5V into back-terminated 50
or 75
cables, and they deliver ±2V to a 75
load, allowing
multiple cables to be driven from a single output.
For implementation of large switch arrays, a low-power
disable mode places the amplifier outputs in a high-
impedance state. Channel selection and output
enable/disable are controlled by four TTL/CMOS-
compatible logic inputs. Each video input is isolated by
an AC-ground pin, which minimizes channel-to-channel
capacitance and reduces crosstalk to 90dB at 10MHz.
The four-channel MAX498 dissipates 390mW (typical)
from ±5VDC power supplies with all output buffers
enabled. Power consumption is reduced to 130mW with
all buffers disabled. The corresponding dissipation for
the three-channel MAX499 is 300mW enabled and
100mW disabled.
