Electrical Specifications

Notes:

1. For OP290, OP291, OP292, OP295, OP296 and OP297, derate linearly 1.67 mA/° C above 25° C (free-air). When used with heat sink (see note 5),

derate linearly 2.07 mA/° C above 65° C (normal use). For OP293 and OP298, when measured in free-air, derate power dissipation linearly 1.43

mW/° C above 25° C. For OP294 and OP299, derate linearly 1.80 mW/° C above 25° C.
