Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC6090/LTC6090-5 is capable of producing peak output
currents in excess of 50mA. Current density limitations within the IC require
the continuous RMS current supplied by the output (sourcing or sinking)
over the operating lifetime of the part be limited to under 50mA (Absolute
Maximum). Proper heat sinking may be required to keep the junction
temperature below the absolute maximum rating. Refer to Figure 7, the
Power Dissipation section, and the Safe Operating Area section of the data
sheet for more information.
Note 3:
The LTC6090C/LTC6090I are guaranteed functional over the
operating junction temperature range –40°C to 85°C. The LTC6090H
is guaranteed functional over the operating junction temperature range
–40°C to 125°C. Specifying the junction temperature range as an operating
condition is applicable for devices with potentially significant quiescent
power dissipation.

Note 4:
The LTC6090C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6090C is designed, characterized, and expected
to meet specified performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures. The LTC6090I is guaranteed to meet
specified performance from –40°C to 85°C. The LTC6090H is guaranteed
to meet specified performance from –40°C to 125°C.
Note 5:
This device includes over temperature protection that is intended
to protect the device during momentary overload conditions. Operation
above the specified maximum operating junction temperature is not
recommended.
Note 6:
Input bias and offset current is production tested with ±15V
supplies. See Typical Performance Characteristics curves of actual typical
