SGM9148

13MHz, 5th-Order Video Driver

with 6dB Gain

GENERAL DESCRIPTION

FEATURES

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.

● Excellent Video Performance

● 5th-Order Reconstruction Filter

● Internal Gain: 6dB

● Rail-to-Rail Output

● SAG Correction Reduces AC Coupling Capacitor

Size

● Input Voltage Range Includes Ground

● AC- and DC-Coupled Input

● Single Power Supply: 3.0V to 5.5V

● Low Power

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.

5mA Typical Supply Current

0.1μA Supply Current when Disabled

● Available in Green SOT-23-6 Package

● -40℃ to +85℃ Operating Temperature Range

SGM9148 has a power-down disable feature that

reduces the supply current to 0.1μA, dramatically

reducing power consumption and prolonging battery

life.

The SGM9148 is available in Green SOT-23-6 package.

It is specified over the -40℃ to +85℃ temperature

range.
