MAX9500/MAX9501 are integrated circuits for filtering and buffering HDTV signals
The MAX9500 and MAX9501 are fully integrated triple‑channel HDTV reconstruction filters. The MAX9500 runs from a single +5 V supply, while the MAX9501 uses dual +5 V supplies. They provide DC‑coupled inputs with very low capacitance and a +6 dB output gain to drive 75 Ω back‑terminated loads.
Key features include a 30 MHz bandwidth at +1.5 dB, >40 dB attenuation at 44.25 MHz, 16‑pin QSOP packaging, and extensive electrical specifications such as low input capacitance (1 pF), output impedance of 8 Ω at 30 MHz, and a PSRR of 60 dB at 100 kHz.
