DESCRIPTION FEATURES
The AMC8214 is a very high frequency video pre-amplifier
system especially for ultra high resolution monitor
applications (1280 × 1024 or higher). In addition to three
matched amplifiers, the AMC8214 contains three gain
adjustment circuits for white balance and three clamp gated
comparators for brightness control. Also, the AMC8214 has
an internally set output DC level of 1.0V, for some
applications, no external output DC level setting is required.
The AMC8214 is built into a 18 pin DIP package,
accommodating very compact and cost effective designs for
color monitor applications. All controls to AMC8214 such
as contrast and gain adjustment are 0V to 4V with high
impedance DC inputs. This makes the system easily
interfaced with 5V DACs in micro computer controlled
systems. Not only working with 8V power supply, The
AMC8214 can be operated directly from the heater of 6.2V,
which provides very low power consumption and enhance
the over all system performance.
! 4VP-P output with 1.7ns Tr/Tf and low
Electrical Magnetic Emission
! Power consumption 40% lower than
12V operated video amplifiers
! Can be Operated at 6.2V supply
voltage for lower power consumption
! 0V to 4V, high impedance DC
controls for Contrast, Gain
Adjustment and Output DC level
setting
# Output stage directly drives most
hybrid or discrete CRT drivers
# Low power ≤ 600mW;
ICC1 + ICC2 Typ. 90mA at full swing
