General DescriptionThe LM7171isa high speed voltage feedback amplifierthat
hasthe slewing characteristicofa current feedback ampli-
fier;yetitcanbe usedinall traditional voltage feedbackam-
plifier configurations.The LM7171is stablefor gainsaslow+2or−1.It providesa very high slewrateat 4100V/μs
anda wide unity-gain bandwidthof200 MHz while consum-
ing only6.5mAof supply current.Itis idealfor videoand
high speed signal processing applications suchas HDSL
and pulse amplifiers. With 100mA output current, the
LM7171canbe usedfor video distribution,asa transformer
driverorasa laser diode driver.
Operationon ±15V power supplies allowsfor large signal
swings and provides greater dynamic range and
signal-to-noise ratio. The LM7171 offers low SFDR and
THD,ideal forADC/DAC systems. Inaddition,the LM7171is
specifiedfor ±5V operationfor portable applications.
The LM7171is builton National’s advanced VIP™III (Verti-
cally integrated PNP) complementary bipolar process.
