Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
This specifi cation implies a typical input offset voltage of 5.7mV at may cause permanent damage to the device. Exposure to any Absolute VCM = 18V and a maximum input offset voltage of 18mV at VCM = 18V. Maximum Rating condition for extended periods may affect device
Note 7:
This parameter is not 100% tested. reliability and lifetime.
Note 8:
Specifi cations apply to 6-lead SOT-23 with shutdown.
Note 2:
A heat sink may be required to keep the junction temperature
