Small S-Video drivers increase battery life and remove glitches in portable video applications
Housed in tiny, ultra-slim μTQFN or chipscale packages, 9MHz low-pass reconstruction filters from Intersil remove quantization noise and switching glitches created by video DACs on an analogue output signal. The devices have integrated gain-of-two buffers and a summer that recombines the S-video signal to provide a composite video output for those applications where the DAC does not provide a composite video out. Coupled with their ultra-small packages and extremely low current consumption, the ISL59114/16 are ideal for portable applications and next-generation video appliances. The ISL59114/16’s tiny 0.5μA power-down current increases the application’s battery life when the amplifier is not in use, in addition to having an extremely low quiescent current during video operation.These parts are targeted at low supply rail applications, and so operate from a single 2.5V to 3.6V supply, making them appropriate for handheld battery voltage ranges. Unlike competitive devices, the ISL59114/16 are offered in ultra-slim μTQFN or chipscale packages that are perfect for thin, handheld applications or space-constrained boards.
The ISL59114/16’s gain-of-two buffers provide enough output drive current and gain to compensate for double-terminated video loads. The device has an output slew rate of 40V/μs, and provides a full rail-to-rail output level.
Target applications for the ISL59114/16 include video amplifiers, portable video players, MP3 players, cable and satellite set-top boxes, video handsets, handheld products, personal video recorders, and HDTVs.
The ISL59114 is available now in a 10-lead μTQFN package, and the ISL59116 is available now in a 9-lead CSP package.
