Note: Thermal limiting circuitry on-chip will shut down the

circuit at a junction temperature of about 165

°C. The de-

vice should never be exposed to this temperature. Opera-

tion above 145

°C junction temperature may degrade

device reliability. See the SLIC Packaging Considerations

for more information.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent device failure. Functionality at or above

these limits is not implied. Exposure to Absolute Maximum

Ratings for extended periods may affect device reliability.

OPERATING RANGES

Commercial (C) Devices

Ambient temperature ............................. 0

°C to +70°C*

AGND/DGND.......................................................... 0 V

BGND with respect to AGND.................... –2 V to +2 V

Load resistance on VTX to ground .............. 10 k

Ω min

Operating Ranges define those limits between which device

functionality is guaranteed.

* Functionality of the device from 0

°C to +70°C is guaranteed

by production testing. Performance from –40

°C to +85°C is

guaranteed by characterization and periodic sampling of

production units.
