TEST LEVEL CODES
All electrical characteristics are subject to the
following conditions:
All parameters having min/max specifications
are guaranteed. The Test Level column indi-
cates the specific device testing actually per-
formed during production and Quality Assur-
ance inspection. Any blank section in the data
column indicates that the specification is not
tested at the specified condition.
LEVEL
TEST PROCEDURE
I
100% production tested at the specified temperature.
II
100% production tested at TA = +25 °C, and sample tested at the
specified temperatures.
III
QA sample tested only at the specified temperatures.
IV
Parameter is guaranteed (but not tested) by design and characteri-
zation data.
V
Parameter is a typical value for information purposes only.
VI
100% production tested at TA = +25 °C. Parameter is guaranteed
over specified temperature range.
ELECTRICAL SPECIFICATIONS
TA=TMIN to TMAX, AVDD=DVDD=OVDD=+5.0 V, VIN=0 to 4 V, CLK=20 MHz, S=10 MSPS, VRHS=4.0 V, VRLS=0.0 V, unless otherwise specified.
