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 product (140MHz) and slew rate
(250V/µs). This makes the OPA2634 an ideal differ-
ential input buffer stage to 3V and 5V CMOS convert-
ers. Unlike other low-power, single-supply operational
amplifiers, distortion performance improves as the
signal swing is decreased. A low 5.6nV/√Hz input
voltage noise supports 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.
