- Quad 2:1 Video Mux Amplifiers
- Reconstruction Filters with 9.5MHz Passband and 47dB Attenuation at 27MHz (MAX9541)
- Fixed Gain of 2V/V
- Input Sync-Tip Clamps
- 2.7V to 3.6V Single-Supply Operation
Video signals are AC-coupled to the inputs of the MAX9541/MAX9542. The input sync-tip clamps set the internal DC level.
The amplifiers have 2V/V gain, and the outputs can be DC-coupled to a 75Ω load, which is the equivalent of two video loads, or AC-coupled to a 150Ω load.
Both the MAX9541/MAX9542 feature a low-power shutdown mode, in which supply current is reduced to 35µA.
