Notes:

1. The AAT3141 is guaranteed to meet performance specification over the -40°C to 85°C operating temperature range and are assured

by design, characterization and correlation with statistical process controls.

2. Codes 2-7 are guaranteed to be within +/-15% of stated current level.

3. Current matching is defined as I_(D-Match)= (I_D- I_AVE)/I_AVE
