MAX4238/MAX4239 Ultra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers
Absolute Maximum Ratings
Power-Supply Voltage (VCC to GND) ...6V Operating Temperature Range ... -40°C to +125°C All Other Pins ..(VGND - 0.3V) to (VCC + 0.3V) Junction Temperature ..+150°C Output Short-Circuit Duration Storage Temperature Range .. -65°C to +150°C (OUT shorted to VCC or GND) ...Continuous Lead Temperature (soldering, 10s) ...+300°C Continuous Power Dissipation (TA = +70°C) Soldering Temperature (reflow) 6-Pin Plastic SOT23 Lead(Pb)-Free Packages ..+260°C (derate 9.1mW/°C above +70°C) ..727mW Packages Containing Lead..+240°C 8-Pin Plastic SO (derate 5.88mW/°C above +70°C) ...471mW 6-Pin TDFN-EP (derate 18.2mW above +70°C) ...1454mW Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
