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.

Contact your local GEC Plessey Semiconductors Customer

Service Centre for further details.

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) + sin 3( t)]

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.
