The MAX11500 is a three-channel, high-definition (HD) video filter integrated circuit that 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.
The MAX11500 is an integrated three‑channel high‑definition video filter that includes transparent input clamps and +6 dB output buffers. It is intended for anti‑aliasing and DAC‑smoothing video applications such as set‑top boxes, hard‑disk recorders, DVD players, and personal video recorders.
Key features include a 6th‑order low‑pass filter with a typical -3 dB bandwidth of 33 MHz, AC‑ or DC‑coupled inputs and outputs, 12 kV HBM ESD protection, and operation from a single +5 V supply in an 8‑pin SO package. The datasheet provides pin descriptions, electrical limits, typical performance curves, and PCB layout recommendations.
