Important Note:
All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually performed during
production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test equipment, specifically the LTX77
Series system. Unless otherwise noted, all tests are pulsed tests, therefor TJ = TC = TA.
Test Level Test Procedure
I
100% production tested and QA sample tested per QA test plan QCX0002.
II
100% production tested at TA = 25°C and QA sample tested at TA = 25°C, TMAX and TMIN per QA test plan QCX0002.
III
QA sample tested per QA test plan QCX0002.
IV
Parameter is guaranteed (but not tested) by Design and Characterization Data.
V
Parameter is typical value at TA = 25°C for information purposes only.
DC Electrical Characteristics
VS=+5V, GND=0V, TA=25°C, VCM=1.5V, VOUT=1.5V, VCLAMP=+5V, VENABLE=+5V, unless otherwise specified.
