AMC DOC. #: AMC8214_A November 2001 AMC8214 ADD MICROTECH CORP. 200MHz RGB VIDEO AMPLIFIER SYSTEM DESCRIPTION FEATURES ! The AMC8214 is a very high frequency video pre-amplifier system especially for ultra high resolution monitor applications (1280 x 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 APPLICATIONS ! ! !
