GB4571 Video Buffer with Precision Strobed DC Restore
DATA SHEET
FEATURES • accurate clamping to within ± 1 mV • less than 1 mV clamping distortion • variable clamping range (VEE + 3.0 V to VCC - 4.5 V) • ultra low differential gain and differential phase • fast recovery from sudden changes in DC offsets • less than ± 0.15° phase delay variation at 3.58 MHz • ± 0.1 dB flatness to 80 MHz • ± 4.5 V to ±13.2 V supply voltage range
DESCRIPTION The GB4571 is a high performance video buffer with DC restore used primarily for accurate back porch clamping. Key features include operation from ± 4.5 V to ± 13.2 V supply voltages, fast recovery from sudden changes in DC offset, ± 0.1 dB flatness to 80 MHz and availability of industry standard DIP and SOIC packages.
