APPLICATIONS INFORMATION
The OPA355 series is a CMOS, high-speed, voltage-feed-
back, operational amplifier designed for video and other
general-purpose applications. It is available as a single, dual,
or triple op amp.
The amplifier features a 200MHz gain bandwidth and
360V/
μ
s slew rate, but it is unity-gain stable and can be
operated as a +1V/V voltage follower.
Its input common-mode voltage range includes ground, al-
lowing the OPA355 to be used in virtually any single-supply
application up to a supply voltage of +5.5V.
PCB LAYOUT
Good high-frequency PC board layout techniques should be
employed for the OPA355. Generous use of ground planes,
short direct signal traces, and a suitable bypass capacitor
located at the V+ pin will assure clean, stable operation.
Large areas of copper also provide a means of dissipating
heat that is generated within the amplifier in normal opera-
tion.
Sockets are definitely not recommended for use with any
high-speed amplifier.
A 10nF ceramic bypass capacitor is the minimum recom-
mended value; adding a 1
μ
F or larger tantalum capacitor in

parallel can be beneficial when driving a low-resistance load.
Providing adequate bypass capacitance is essential to achiev-
ing very low harmonic and intermodulation distortion.
OPERATING VOLTAGE
The OPA355 is specified over a power-supply range of +2.7V
to +5.5V (
±
1.35V to
±
2.75V). However, the supply voltage
may range from +2.5V to +5.5V (
±
1.25V to
±
2.75V). Supply
voltages higher than 7.5V (absolute maximum) can perma-
nently damage the amplifier.
Parameters that vary significantly over supply voltage or
temperature are shown in the Typical Characteristics section
of this data sheet.
ENABLE FUNCTION
The OPA355 can be enabled by applying a TTL HIGH
voltage level to the Enable pin. Conversely, a TTL LOW
voltage level will disable the amplifier, reducing its supply
current from 8.3mA to only 3.4
μ
A per amplifier. Independent
Enable pins are available for each channel, providing maxi-
mum design flexibility. For portable battery-operated applica-
tions, this feature can be used to greatly reduce the average
current and thereby extend battery life.
