The MAX11504/MAX11505 integrated filters offer four channels of 5th order filters for standard-definition video and include +6dB output buffers on each channel. These video filters are ideal for anti-aliasing and DAC smoothing in applications such as set-top boxes, security systems, digital video recorders (DVRs), DVD players, and personal video recorders. The MAX11504/MAX11505 video inputs feature a transparent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly coupled. The 5th order filters provide a bandwidth of 8.6MHz (typical). The MAX11504 offers a flat passband response on all channels. The MAX11505 offers a 0.8dB peaking passband response on Channel 1, resulting in a bandwidth of 8.9MHz (typical) and a flat passband response on all other channels. Each channel includes an output buffer with a gain of +6dB capable of driving a full 2VP-P video signal into two standard 150Ω (75Ω back terminated) video loads. The buffers drive either AC- or DC-coupled loads and assure a blanking level below 1V after the back-match resistor. The MAX11504/MAX11505 operate from a single +5V supply and are available in the 0°C to +70°C commercial temperature range. These devices are available in small 10-pin µMAX® packages.
The MAX11504 and MAX11505 are integrated video filters that provide four channels of 5th‑order low‑pass filtering for standard‑definition video. Each channel includes a transparent input clamp, a +6 dB output buffer, and can drive two standard 150 Ω video loads. The devices operate from a single +5 V supply and are rated for commercial temperature ranges (0 °C to +70 °C).
Typical applications include set‑top‑box receivers, digital video recorders, security video systems, DVD players, and personal video recorders. The datasheet includes pin descriptions, absolute maximum ratings, electrical characteristics, frequency response graphs, layout recommendations, and package information.
