235 MHz Tiny Low Power Voltage Feedback Amplifier
General Description
The LM7121isa high performance operational amplifier
which addressesthe increasingAC performance needsof
video and imaging applications, andthe size and power
constraintsof portable applications.
The LM7121 can operate overa wide dynamic rangeof
supply voltages, from5V (single supply)upto g15V (see
the Application Information sectionfor more details).Itof-
fersan excellent speed-power product delivering 1300V/ms
and235 MHz Bandwidth (b3dB,AV ea1). Anotherkey
featureofthis operational amplifieris stability while driving
unlimited capacitive loads.
Duetoits Tiny SOT23-5 package,the LM7121is idealfor
designs where spaceand weightare thecritical parameters.
The benefitsofthe Tiny packageare evidentin small porta-
ble electronic devices, suchas cameras, andPC video
cards. Tiny amplifiersareso smallthat theycanbe placed
anywhereona board closetothe signal sourceor nearthe
inputtoan A/D converter.
