SGM9126
6-Channel, 5th-Order, Standard
Definition Video Filter Driver
PRODUCT DESCRIPTION
The SGM9126 is a low voltage, 6-channel 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.
SGM9126 offers 6dB gain rail-to-rail output driver and
5th-order output reconstruction filter on all six channels.
It has 8MHz -3dB bandwidth and 35V/µs slew rate.
SGM9126 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 an ultra-low 44mA quiescent
current, the SGM9126 is ideally suited for battery
powered applications.
SGM9126 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 SGM9126
can be configured as DC- or AC-coupled output.
The SGM9126 is available in Green TSSOP-14
package. It operates over an ambient temperature
range of -40to +85.
