General Note: Devices are ESD protected; however, handling precautions are recommended. All limits guaranteed by testing or statistical analysis.
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when
operating the device outside its recommended operating ratings.
Note 2: I/O pin voltage is any external voltage to which an input or output is referenced.
Note 3:
Note 4:
Note 5:
The maximum allowable power dissipation is a function of the maximum junction temperature, T_J(max); the junction-to-ambient thermal
resistance, θ_JA; and the ambient temperature, T_A. The maximum allowable power dissipation at any ambient temperature is calculated using:
P_D = (T_J(max) – T_A) / θ_JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
Thermal resistance, θ_JA, applies to a part soldered on a printed-circuit board.
Human body model, 1.5k in series with 100pF.
Note 6: Short circuit may cause the device to exceed maximum allowable power dissipation. See Note 3.
Note 7: Shorting V_OUT to V+ when V+ > 10V may damage the device.
Note 8: Limited by internal bias-network resistors. Power supply must be “clean.” Power supply should be bypassed as shown in typical application
circuit.
Note 9: The gain error specification applies to differential, inverting, and noninverting gains.
Note 10: Since the part is specified in a single-supply configuration, the output load (R_L) is a Thevenin equivalent value. The actual load consists of 2 ×
R_L to ground and 2 × R_L to the supply (V+).
