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:

The maximum allowable power dissipation is a function of the maximum junction temperature, T

J(max); the junction-to-ambient thermal

resistance,

JA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using:

D = (TJ(max) – TA) / θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.

Note 4:

Thermal resistance,

JA, applies to a part soldered on a printed-circuit board.

Note 5:

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 ×

L to ground and 2 × RL to the supply (V+).
