SGM9121
8MHz, 5th-Order Video Driver
with 6dB Gain
GENERAL DESCRIPTION
The SGM9121 is a single rail-to-rail 5th-order output
reconstruction filter with a -3dB bandwidth of 8MHz and
35V/µs slew rate. Operating from single power supply
ranging from 3.0V to 5.5V and sinking an ultra-low 6mA
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 0.1μA, dramatically
reducing power consumption and prolonging battery
life.
It operates over an ambient temperature range of -40℃
to +85℃.

NOTES:
1. A 10kΩ resistor must be serially connected to DISABLE
pin.
2. Power supply VCC must be sequenced on first before input
video signals.
