SGM9121
8MHz, 5th-Order Video Driver
with 6dB Gain
PRODUCT DESCRIPTION
The SGM9121 is a single rail-to-rail 5th-order output
reconstruction filter with a -3dB bandwidth of 8MHz and
34.8V/µs slew rate. Operating from single power supply
ranging from 3.0V to 5.5V and sinking an ultra-low 7mA
quiescent current, the SGM9121 is ideally suited for low
power, battery-operated applications.
SGM9121 employs an internal level shift circuit that
avoids sync-pulse clipping and allows DC-coupled output.
If AC coupling is preferred, the SGM9121 offers a
sag-correction feature that significantly reduces the size
of the output coupling capacitor.
SGM9121 has a power-down disable feature that
reduces the supply current to 0.72μA, dramatically
reducing power consumption and prolonging battery life.
It is specified over the extended -40°C to +85°C
temperature range.
