OPA2650
Dual Wideband, Low Power Voltage Feedback
OPERATIONAL AMPLIFIER
DESCRIPTION
FEATURES
The OPA2650 is a dual, low power, wideband voltage
feedback operational amplifier. It features a high band-
width of 360MHz as well as a 12-bit settling time of
only 20ns. The low distortion allows its use in commu-
nications applications, while the wide bandwidth and
true differential input stage make it suitable for use in
a variety of active filter applications. Its low distortion
gives exceptional performance for telecommunica-
tions, medical imaging and video applications.
● LOW POWER: 50mW/Chan.
● UNITY GAIN STABLE BANDWIDTH:
360MHz
● FAST SETTLING TIME: 20ns to 0.01%
● LOW HARMONICS: –77dBc at 5MHz
● DIFFERENTIAL GAIN/PHASE ERROR:
0.01%/0.025°
● HIGH OUTPUT CURRENT: 85mA
The OPA2650 is internally compensated for unity-
gain stability. This amplifier has a fully symmetrical
differential input due to its “classical” operational
amplifier circuit architecture. Its unusual combination
of speed, accuracy and low power make it an outstand-
ing choice for many portable, multi-channel and other
high speed applications, where power is at a premium.
APPLICATIONS
● HIGH RESOLUTION VIDEO
● BASEBAND AMPLIFIER
● CCD IMAGING AMPLIFIER
● ULTRASOUND SIGNAL PROCESSING
● ADC/DAC GAIN AMPLIFIER
● ACTIVE FILTERS
The OPA2650 is also available in single (OPA650)
and quad (OPA4650) configurations.
