Three-Channel, High-Definition Video Filter

HD Video Filter Buffer with Improved Stopband Attenuation, 12kV HBM ESD Protection

Please check latest availability status for a specific part variant.


The MAX11500 integrated three-channel high-definition (HD) video filter includes input video clamps and output buffers. This device is ideal for anti-aliasing and DAC smoothing video applications such as set-top boxes, hard-disk recorders (HDRs), DVD players, and personal video recorders.

The 6th-order channel filters have a typical -3dB bandwidth of 33MHz. Each channel has an output buffer with a gain of +6dB and can drive a full 2VP-P video signal into one standard 150Ω video load. These buffers can drive either an AC- or DC coupled load such that the blanking level voltage after the backmatch resistor is less than 1V.

The video inputs feature a transparent clamp for AC- and DC-coupled input signals. If the input signal does not go below ground, the input clamp is inactive, thus enabling DAC outputs to be DC-coupled to the input. The device operates from a single +5V supply, is offered in the upper commercial 0°C to +85°C temperature range, and is available in a small 8-pin SO package.
