Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltage values are with respect to ground with GND and OGND
wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below VSS or above VDD, they
will be clamped by internal diodes. This product can handle input currents
greater than 100mA below VSS or above VDD without latchup.
Note 4: When these pin voltages are taken below VSS they will be clamped
by internal diodes. This product can handle input currents greater than
100mA below VSS without latchup. GAIN is not clamped to VDD. When CLK
is taken above VDD, it will be clamped by an internal diode. The CLK pin
can handle input currents of greater than 100mA above VDD without
latchup.
Note 5: VDD = 5V, VSS = – 5V or 0V, fSAMPLE = 5MHz, tr = tf = 5ns unless
otherwise specified.
