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/µs). 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.
