I

Reference voltage in (bottom)

REFBS

22

Reference voltage (bottom). When using the internal voltage divider to generate a nominal 2-V reference,

this terminal is shorted to the REFB terminal and the REFTS terminal is shorted to the REFT terminal (see

Figure 21).

† 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.
