(1)

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is ensured. Operating Ratings do not imply specified performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics table.

(2)

All voltages are with respect to the potential at the GND pins.

(3)

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(4)

Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 150°C (typ.) and

disengages at TJ = 130°C (typ.).

(5)

The Human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin. (MIL-STD-883 3015.7) . TI

recommends that all integrated circuits be handled with appropriate precautions.

−30°C to +85°C

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is ensured. Operating Ratings do not imply specified performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics table.

(2)

All voltages are with respect to the potential at the GND pins.

(3)

In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may

have to be de-rated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =

125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the

part/package in the application (

θJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (θJA × PD-MAX).

THERMAL PROPERTIES

Junction-to-Ambient Thermal

Resistance (

θJA), YPA10 Package

(1)

Junction-to-ambient thermal resistance (

θJA) is taken from thermal measurements, performed under the conditions and guidelines set

forth in the JEDEC standard JESD51-2. A 1" x 1", 4 layer, 1.5oz. Cu board was used for the measurements.
