FEATURES
DESCRIPTION
D
EXCELLENT VIDEO PERFORMANCE
0.5dB GAIN FLATNESS: 20MHz
The OPA358, OPA359, and OPA360 high-speed video
amplifiers are optimized for 3V single-supply operation.
The output swings within 200mV of the positive
power-supply rail and 70mV to the negative rail with a
typical video load. The input common-mode range
includes GND and extends to within 1V of the positive
power supply. These devices offer excellent video
performance: 0.5dB gain flatness is 20MHz, differential
gain is 0.02%, and differential phase is 0.05°. Quiescent
current is only 5mA per channel.
DIFF. GAIN: 0.02%, DIFF. PHASE: 0.055

The OPA359 and OPA360 have been optimized for
space-sensitive applications by integrating internal G = 2
setting resistors, a 2-pole Digital-to-Analog converter
(DAC) anti-aliasing filter (OPA360 only), and sag
correction (OPA359 and OPA360) to reduce the size of the
output coupling capacitors. See the Available Options
table below. For gains other than 6dB, please contact your
local TI sales representative.

MicroSIZE PACKAGE: SC70-6, SOT23-6
The final product will have additional circuitry that prevents the output
from saturating, even with 0V sync tip level at the input video signal.
SPECIAL FEATURES
D
INTERNAL GAIN = 2 (OPA359 and OPA360)
2-POLE ANTI-ALIASING FILTER
(OPA360 only)
In shutdown mode, the quiescent current is reduced to
<5µA, dramatically reducing power consumption. This is
especially important in battery-operated equipment such
as digital still cameras (DSCs) or digital camcorders.

SAG CORRECTION (OPA359 and OPA360)
− Reduces Coupling Capacitor Size
The OPA358, OPA359, and OPA360 are available in
SC70-6 and SOT23-6, the smallest video packages
currently available. For higher channel counts, please
contact your local TI sales representative.
