(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

The device is rated to MSL2 260°C, as per the JSTD-020 specification.

7.2 Electrical Characteristics

TA = –40°C to 85°C, +VA = 5 V, +VBD = 5 V to 2.375 V, Vref = 4 V, and fSAMPLE = 500 kHz, unless otherwise noted.
