DESCRIPTION
Analog ground
I Analog input
I Clock input
Digital ground
O Digital data out. D1:LSB, D8:MSB
I Output enable. When OE = L, data is enabled. When OE = H, D1−D8 is high impedance.
Analog VDD
Digital VDD
I ADC reference voltage in (bottom)
Reference voltage (bottom). When using the internal voltage divider to generate a nominal 2-V reference, the
REFBS terminal is shorted to the REFB terminal and the REFTS terminal is shorted to the REFT terminal (see
Figure 13 and Figure 14).
I Reference voltage in (top)
Reference voltage (top). When using the internal voltage divider to generate a nominal 2-V reference, the
REFTS terminal is shorted to the REFT terminal and the REFBS terminal is shorted to the REFB terminal (see
Figure 13 and Figure 14).

† _{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.
