NSC LM6182IN, LM6182IMX, LM6182IM, LM6182AIN Datasheet
LM6182
Dual 100 mA Output, 100 MHz Current Feedback
Amplifier
General 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 50Ω
or 75Ω 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is intended to be functional, but device parameter specifications may not be guaranteed under these conditions. For guaranteed specifications and test conditions, see
the Electrical Characteristics.
Note 2: Human body model 100 pF and 1.5 kΩ.
Note 3: The typical junction-to-ambient thermal resistance of the molded plastic DIP(N) soldered directly into a PC board is 95˚C/W. The junction-to-ambient thermal
resistance of the S.O. surface mount (M) package mounted flush to the PC board is 70˚C/W when pins 1,4,8,9 and 16 are soldered to a total of 2 in
2
1 oz copper
trace. The S.O. (M) package must have pin 4 and at least one of pins 1,8,9, or 16 connected to V− for proper operation.
Note 4: Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowable junction temperature of 150˚C. Each am-
plifier of the LM6182 is short circuit current limited to 100 mA typical.
Note 5: Typical values represent the most likely parametric norm.
Note 6: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (boldface type).
Note 7: Each amp excited in turn with 100 kHz to produce Vo=2 Vpp. Results are input referred.
Note 8: Measured from +25%to +75%of output waveform.
Note 9: Also available per the Standard Military Drawing, 5962-9460301MCA.
Note 10: For guaranteed military specifications see military datasheet MNLM6182AM-X.
