DESCRIPTION

The OPA360 high-speed amplifier is optimized for 3V

portable video applications. It has been specifically

designed

to

be

compatible

with

digital-to-analog

converters (DACs) embedded in video processors, such

as Texas Instruments’ family of Digital Media Processors

and others. The input common-mode range includes

GND, which allows the Video-DAC to be DC-coupled to

the OPA360.

The output swings within 25mV of GND and 300mV to V+

with a standard back-terminated video load (150

Ω). An

internal level shift circuit prevents the output from

saturating with 0V input, thus preventing sync-pulse

clipping in common video circuits. Therefore, the OPA360

is ideally suited for DC-coupling to the video load. If

AC-coupling

is

preferred,

the

OPA360

offers

a

sag-correction feature that significantly reduces the size of

the output coupling capacitor.

The OPA360 has been optimized for space-sensitive

applications by integrating sag-correction, internal gain

setting resistors (G = 2), and a 2-pole video-DAC

reconstruction filter.

In shutdown mode, the quiescent current is reduced to

< 5

µA, dramatically reducing power consumption and

prolonging battery life.

The OPA360 is available in the tiny 2mm x 2.1mm SC70-6

package.
