Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum specifications for extended periods may affect device
reliability.

Die Thickness:
The standard thickness of Analog Devices
bipolar dice is 24 mil ± 2 mil.
Die Dimensions:
The dimensions given have a tolerance of
±2 mil.
Backing:
The standard backside surface is silicon (not plated).
Analog Devices does not recommend gold-backed dice for most
applications.
Edges:
A diamond saw is used to separate wafers into dice, thus
providing perpendicular edges halfway through the die. In
contrast to scribed dice, this technique provides a more uniform
die shape and size. The perpendicular edges facilitate handling
(such as tweezer pickup), while the uniform shape and size
simplify substrate design and die attach.
Top Surface:
The standard top surface of the die is covered by a
layer of glassivation. All areas are covered except bonding pads
and scribe lines.
Surface Metallization:
The metallization to Analog Devices
bipolar dice is aluminum. Minimum thickness is 10,000 Å.
Bonding Pads:
All bonding pads have a minimum size of
4.0 mil by 6.0 mil. The passivation windows have a minimum
size of 3.6 mil by 5.6 mil.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
