LM6181
100 mA, 100 MHz Current Feedback Amplifier
General Description
The LM6181 current-feedback amplifier offers an unparal-
leled combination of bandwidth, slew-rate, and output cur-
rent. The amplifier can directly drive up to 100 pF capacitive
loads without oscillating and a 10V signal into a 50Ω or 75Ω
back-terminated coax cable system over the full industrial
temperature range. This represents a radical enhancement
in output drive capability for an 8-pin DIP high-speed ampli-
fier making it ideal for video applications.
Built on National’s advanced high-speed VIP
Integrated PNP) process, the LM6181 employs current-
feedback providing bandwidth that does not vary dramati-
cally with gain; 100 MHz at A
With a slew rate of 2000V/µs, 2nd harmonic distortion of −50
dBc at 10 MHz and settling time of 50 ns (0.1%) the LM6181
dynamic performance makes it ideal for data acquisition,
high speed ATE, and precision pulse amplifier applications.
