SGM9148
13MHz, 5th-Order Video Driver
with 6dB Gain
GENERAL DESCRIPTION
The SGM9148 is a single rail-to-rail 5th-order output
reconstruction filter with a -3dB bandwidth of 13MHz
and 63V/µs slew rate. Operating from single power
supply ranging from 3.0V to 5.5V and sinking 5mA
quiescent current, the SGM9148 is ideally suited for
low power, battery-operated applications.
SGM9148 employs an internal level shift circuit that
avoids sync-pulse clipping and allows DC-coupled
output. If AC coupling is preferred, the SGM9148 offers
a sag-correction feature that significantly reduces the
size of the output coupling capacitor.
SGM9148 has a power-down disable feature that
reduces the supply current to 0.1μA, dramatically
reducing power consumption and prolonging battery
life.
