Three-Channel, Standard-Definition Video Filters

SD Video Filter Buffers with Improved Stop-Band Attenuation and 12kV ESD Protection

Please check latest availability status for a specific part variant.


The MAX11501/MAX11502 integrated filters offer three 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 MAX11501/MAX11502 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 typical -3dB bandwidth 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 backmatch 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 available in small 8-pin SO packages.
