LM6317 120 MHz Fast Settling Low Power Voltage Feedback Amplifier
November 1995
LM6317
120 MHz Fast Settling Low Power
Voltage Feedback Amplifier
General Description
The LM6317 is a high speed unity-gain stable voltage feed-
back amplifier that consumes only 40 mW of quiescent pow-
er Operating at
g
5V power supply the LM6317 provides
excellent AC performance such as 120 MHz of unity-gain
bandwidth 1500V
ms
of slew rate and 80 dB of SFDR
The LM6317 has the slew characteristic of a current feed-
back amplifier yet it can be used in all traditional amplifier
configurations The high output current and good stability
with capacitive load of LM6317 makes it ideal for driving
cables With its unity-gain stability fast settling time and low
output impedance the LM6317 can be used to buffer A D
converters The LM6317 also has very low input voltage and
current noise high CMRR and PSRR desirable in precision
applications such as ATE systems
