DESCRIPTION
The OPA634 and OPA635 are low power, voltage-
feedback, high-speed amplifiers designed to operate on
+3V or +5V single-supply voltages. Operation on
5V
or +10V supplies is also supported. The input range
extends below ground and to within 1.2V of the positive
supply. Using complementary common-emitter outputs
provides an output swing to within 30mV of ground and
140mV of positive supply. The high output drive cur-
rent, low differential gain and phase errors make them
ideal for single-supply composite video line driving.
Low distortion operation is ensured by the high gain
bandwidth (140MHz) and slew rate (250V/
s). This
makes the OPA634 and OPA635 ideal input buffer
stages to 3V and 5V CMOS converters. Unlike other low
power, single-supply operational amplifiers, distortion
performance improves as the signal swing is decreased.

A low 5.6nV input voltage noise supports wide dynamic
range operation. Multiplexing or system power reduc-
tion can be achieved using the high-speed disable line
with the OPA635. Power dissipation can be reduced to
zero by taking the disable line High.
The OPA634 and OPA635 are available in an industry
standard SO-8 package. The OPA634 is also available in
an ultra-small SOT23-5 package, while the OPA635 is
available in the SOT23-6. Where lower supply current
and speed are required, consider the OPA631 and
OPA632.

ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from perfor-
mance degradation to complete device failure. Burr-Brown Corpo-
ration recommends that all integrated circuits be handled and stored
using appropriate ESD protection methods.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes
could cause the device not to meet published specifications.
