Low Pass Filter
The MAX7440/MAX7441/MAX7442 are 6-channel video reconstruction filters. They are ideal for anti-aliasing and digital-to-analog (DAC) reconstruction video applications. Each channel of the devices combine a continuous-time low pass filter with high frequency boost options and a unity-gain amplifier. The filter achieves 40 dB of stopband rejection at 27 MHz with a flat passband of ± 0.5 dB ripple. The devices are packaged in a 14-pin SO package. Temperature range is 40°C to +85°C.
