FEATURES
DESCRIPTION
● HIGH BANDWIDTH: 150MHz (G = +2)
● +3V AND +5V OPERATION
● INPUT RANGE INCLUDES GROUND
● 4.8V OUTPUT SWING ON +5V SUPPLY
● HIGH OUTPUT CURRENT: 80mA
● HIGH SLEW RATE: 250V/µs
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 INPUT VOLTAGE NOISE: 5.6nV/√HZ
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.
APPLICATIONS
● DIFFERENTIAL RECEIVERS/DRIVERS
● ACTIVE FILTERS
● MATCHED I AND Q CHANNEL AMPLIFIERS
● CCD IMAGING CHANNELS
● LOW POWER ULTRASOUND
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.
