SGM9119 Triple, 5th-Order, Standard Definition Video Filter Driver
PRODUCT DESCRIPTION
The SGM9119 is a low voltage, triple video amplifier with integrated reconstruction filters and input clamps. Specially suited for standard definition video signals, this device is ideal for a wide range of television and set-top box applications.
SGM9119 offers 6dB gain rail-to-rail output driver and 5th-order output reconstruction filter on all three channels. It has 8MHz -3dB bandwidth and 31.5V/µs slew rate. SGM9119 provides improved image quality compared with passive LC filters and discrete drivers solution. Operating from single power supply ranging from 3.3V to 5.5V and sinking a low 21mA quiescent current, the SGM9119 is ideally suited for battery powered applications.
SGM9119 can be DC-coupled or AC-coupled with input video signal, such as the output stage of DAC to eliminate out-of-band noise. The output in SGM9119 can be configured as DC- or AC-coupled output.
The SGM9119 is available in Green SOIC-8 and MSOP-8 packages. It operates over an ambient temperature range of -40℃ to +85℃.

NOTE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at any time. Please contact SGMICRO sales office to get the latest datasheet.
