ISL59830A中文资料INTERSIL数据手册PDF规格书

The ISL59830A is a revolutionary device that allows true

single-supply operation of video amplifiers. The device runs

off a single 3.3V supply and generates the required negative

voltage internally. This allows for DC-accurate coupling of

video onto a 75Ω double-terminated line. Since the buffers

have an integrated 6dB gain, the only external components

required are the 75Ω termination resistors and a small

capacitor. An input reference voltage can be supplied to shift

the analog video level down by an amount equal to the

reference (typically 0.6V).
