AverLogic Technologies AL875
The AL875 is a high-speed triple 8-bit monolithic analog-to-digital converter (ADC) designed for digitizing RGB graphics/video signal or other applications. Its 110 MHz conversion rate can support display resolution up to 1280x1024 at 60Hz. The AL875 accepts 0.6~2.0V analog input range without using pre-amplifiers which may reduce the overall S/N ratio.APPLICATIONS
