6.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT
Supply voltage, Vs = (V+) - (V-) –0.3 6 V
Input pins Voltage (2) (3) Common mode (V-) - 0.3 (V+) + 0.3 V
Differential (V-) - 0.3 (V+) + 0.3 V
Input pins Current -10 10 mA
Output short current (4) Continuous Continuous
Operating temperature –40 125 °C
Storage temperature, Tstg –65 150 °C
Junction temperature 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Not to exceed -0.3V or +6.0V on ANY pin, referred to V-
(3) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should be current-limited to 10 mA or less.
(4) Short-circuit to Vs/2, one amplifer per package. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±250
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. Pins listed as ±2000 V may actually have higher performance.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. Pins listed as ±750 V may actually have higher performance.

6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
Supply voltage (V+ – V–) 1.6 5.5 V
Specified temperature -40 125 °C
