LM6181

LM6181 100 mA, 100 MHz Current Feedback Amplifier May 1998 LM6181 100 mA, 100 MHz Current Feedback Amplifier General Description The LM6181 current-feedback amplifier offers an unparalleled combination of bandwidth, slew-rate, and output current. 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 amplifier making it ideal for video applications. Built on National’s advanced high-speed VIP™ II (Vertically Integrated PNP) process, the LM6181 employs currentfeedback providing bandwidth that does not vary dramatically with gain; 100 MHz at AV = −1, 60 MHz at AV = −10. 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.
