Voltage on any pin
Current through any I/O pin
V_SS-0.3V to V_DD +0.3V
±10mA
Storage temperature (see note)
-65°C to +125°C
Operating temperature range (commercial) 0°C to +70°C
Operating temperature range (industrial) -40°C to +85°C
Stresses above those listed in the Absolute Maximum
Ratings may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at
these conditions, or at any other condition above those indicated
in the operations section of this specification, is not implied.
Exposure to Absolute Maximum Rating conditions for extended
periods may affect device reliability.
NOTE: These temperature ranges apply to all package types.
Many package types are available and extended temperature
ranges can be offered for some packages. Further information
is available on request.

PRODUCT DESIGNATION
Two standard options exist, defining waveform shape.
These are designated MA838-1 and MA838-2 as follows:
MA838-1
Sine + third harmonic at one sixth the amplitude of the
fundamental:
x(t) = A [sin ( t) +1 sin 3( t)]
6
MA838-2
Pure sinewave:
x(t) = A [sin ( t)]
Additional wave shapes can be implemented to order, provided
they are symmetrical about the 90°, 180° and 270° axes.
