Description The LM6182 dual current feedback amplifier offers an unparalleled combination of bandwidth, slew-rate, and output current. Each amplifier can directly drive a 2V signal into a 50 Ohm or 75 Ohm back-terminated coax cable system over the full industrial temperature range. This represents a radical enhancement in output drive capability for a dual 8-pin high-speed amplifier making it ideal for video applications.
Built on National's advanced high-speed VIP II™ (Vertically Integrated PNP) process, the LM6182 employs current-feedback providing bandwidth that does not vary dramatically with gain; 100 MHz at Av = -1, 60 MHz at Av = -10. With a slew rate of 2000 V/µsec, 2nd harmonic distortion of -50 dBc at 10 MHz and settling time of 50 ns (0.1%), the two independent amplifiers of the LM6182 offer performance that is ideal for data acquisition, high-speed ATE, and precision pulse amplifier applications.
See the LM6181 data sheet for a single amplifier with these same features.
