The MAX11501/MAX11502 integrated filters offer three channels of 5th-order filters for standard-definition video and include +6dB output buffers on each chan- nel. 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 MAX11501/MAX11502 video inputs feature a trans- parent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly cou- pled. The 5th-order filters provide a typical -3dB band- width of 8.6MHz (MAX11501) and 8.9MHz (MAX11502) and offer either a flat passband response (MAX11501) or a +0.8dB peaking passband response (MAX11502) on all 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 of below 1V after the back- match resistor. The MAX11501/MAX11502 operate from a single +5V supply and are available in the upper commercial 0°C to +85°C temperature range. These devices are avail- able in small 8-pin SO packages.
The MAX11501 and MAX11502 are three‑channel, 5th‑order low‑pass video filters designed for standard‑definition video applications such as set‑top boxes, DVRs, and DVD players. Each channel provides a +6 dB output buffer, a transparent input clamp that supports AC‑ or DC‑coupled signals, and can drive two 75 Ω video loads.
The devices operate from a single +5 V supply, are available in an 8‑pin SO package, and are rated for a temperature range of 0 °C to +85 °C. Detailed electrical characteristics, absolute maximum ratings, and typical operating conditions are provided for both parts.
