The MAX9657 is a small, low-power, quad video amplifier with input sync-tip clamps. It features a bandwidth of 15MHz, making it suitable for not only standard-definition video signals, but also video graphics array (VGA) signals with a 640 x 480 resolution at up to 85Hz refresh rate.
The MAX9658 is a quad video amplifier with integrated lowpass filters and input sync-tip clamps. The lowpass filters typically have ±1dB passband flatness out to 9.5MHz and 47dB attenuation at 27MHz. Specially suited for composite video signals, the MAX9658 is ideal for performing anti-alias filtering at the inputs of a digital video recorder or for performing reconstruction filtering at the outputs of a SCART set-top box.
Both devices require that the incoming video signals be AC-coupled to the inputs. The input sync-tip clamps set the internal DC level of the video signals.
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 MAX9657/MAX9658 feature a low-power shutdown mode, in which supply current is reduced to 35µA.
The MAX9657/MAX9658 operate from a single 2.7V to 3.6V supply, are specified over the -40°C to +125°C automotive temperature range, and are offered in a small, 16-pin QSOP package.
