Note 1: "Absolute Maximum Ratings" are those parameter values beyond which the life and operation of the device cannot be guaranteed. The stating herein of
these maximums shall not be construed to imply that the device can or should be operated at or beyond these values. The table of "Electrical Characteristics"
specifies acceptable device operating conditions.
Note 2: Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated referenced to
V_EE = 0 Volts.
Note 3: Typical values are stated for V_CC = +3.3V and T_A = +25°C.
Note 4: Specification is guaranteed by characterization.
Note 5: The LMH0384 can be optimized for different launch amplitudes via the SPI.
