DESCRIPTION
The OPA2634 is a dual, low power, voltage-feedback,
high-speed operational amplifier designed to operate
on +3V or +5V single-supply voltage. 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-emit-
ter outputs provides an output swing to within 30mV
of ground and 140mV of positive supply.
Low distortion operation is ensured by the high gain
bandwidth (140MHz) and slew rate (250V/
s). This
makes the OPA2634 an ideal differential input buffer
stage to 3V and 5V CMOS converters. Unlike other
low power, single-supply operational amplifiers, dis-
tortion performance improves as the signal swing is
decreased. A low 5.6nV/
Hz input voltage noise sup-
ports wide dynamic range operation.
The OPA2634 is available in an industry-standard dual
pinout SO-8 package. Where a single channel, single-
supply operational amplifier is required, consider the
OPA634 and OPA635. Where lower supply current
and speed are required, consider the OPA2631.

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.
