Dual Very Low Noise Amplifier
Absolute Maximum Ratings (T = 25°C)
A
Values beyond absolute maximum ratings can cause the device to be pre-
maturely damaged. Absolute maximum ratings are stress ratings only
and functional device operation is not implied

Important Note:
All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are at the
specified temperature and are pulsed tests, therefore: TJ = TC = TA.
Electrical Characteristics
VS+ = +12V, VS - = -12V, RL = 500W and CL = 3pF to 0V, RF = RG = 620W, and TA = 25°C unless otherwise specified.
