OPERATIONAL AMPLIFIER  
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.
