Notes:

1. For OP290, OP291, OP292, OP295, OP296 and OP297, refer to graph of Maximum Peak Pulse Current vs Pulse Width.

2. For all OPs in this series, RMA flux is recommended. Duration can be extended to 10 second maximum when soldering. A maximum of 20 grams

force may be applied to the leads when flow soldering.

3. For OP290, OP291, OP292, OP295, OP296 and OP297, measured in free-air. Derate linearly 3.33 mW/° C above 25° C.

4. For OP290, OP291and OP292, mounted on 1/16” (1.6 mm) thick PCBoard with each lead soldered through 80 mil square lands 0.250” (6.35 mm)

below flange of device. Derate linearly 5.33 mW/°C above 62.5°. For OP293 and OP298, mounted on 1/16” (1.60 mm) thick PCBoard with each

lead soldered through 80 mil square lands 0.250” (6.35 mm) below flange of device. Derate power dissipation linearly 2.00 mW/°C above 25° C

(normal use). For OP295, OP296 and OP297, mounted on 1/16” (1.6 mm) thick PCBoard with each lead soldered through 80 mil square lands

0.250” (6.35 mm) below flange of device. Derate linearly 5.33 mW/°C above 25° C.

5. Immersed in silicone fluid to simulate infinite heat sink. For OP290, OP291 and OP292, derate linearly 11.1 mW/°C above 95°C. For OP293 and

OP298, derate power dissipation linearly 2.50 mW/° C above 25° C. For OP295, OP296 and OP297, derate linearly 11.1 mW/° C above 25° C.
