GENERAL DEscriptION

The SGM9149 is a rail-to-rail, 3-channel, 5th-order output reconstruction filter with input clamps which can operate from 3.0V to 5.5V single power supply, while consuming an ultra-low 21mA current. The device is optimized for low power, wide range of television and set-top box applications.

The device has a -3dB bandwidth of 13MHz and 61V/μs slew rate, allowing DC- or AC-coupled output. SGM9149 can be DC-coupled or AC-coupled with input video signal to eliminate out-of-band noise, such as the output stage of DAC.

The SGM9149 is available in Green SOIC-8 and MSOP-8 packages. It operates over an ambient temperature range of -40℃ to +85℃.
