AMC8213

DESCRIPTION

FEATURES

The AMC8213 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 AMC8213 contains three gain adjustment circuits for white

balance, three clamp gated comparators for brightness control, and

the OSD mixer. Also, the AMC8213 has an internally set output

DC level of 1.0V, for some applications, no external output DC

level setting is required. The AMC8213 is built into a 22 pin DIP

package, accommodating very compact and cost effective designs

for those applications requiring OSD. All controls to AMC8213

such as contrast, gain adjustment, and fast blanking 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 AMC8213 can be

operated directly from the heater of 6.2V, which provides very

low power consumption and enhance the over all performance.

Electrical Magnetic Emission

Power consumption 40% lower than 12V

operated video amplifiers

Can be Operated at 6.2V supply voltage for

lower power consumption

Fast Blanking for OSD inputs, typical 7ns

Fast OSD switching time, typcial 3ns

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
