PACKAGE/ORDER I FOR ATIO
ABSOLUTE AXI U RATI GS
LTK001
Note A: The polarity of the amplifier is indicated by the 0 or 1 in the part
number. An LT1025 with a 0 identifier is properly matched with an LTKA00,
while an LT1025 with a 1 identifier should be used with an LTKA01.
Consult factory for parts specified with wider operating temperature ranges.
