AI
External 1% Bias Resistor. Requires a 12.1k ohm (1%) resistor to ground
connected as described in the Analog Layout Guidelines. The nominal
voltage is 1.2V and the resistor will dissipate approximately 1mW of power.

P
+1.2V (Core voltage) - 1.2V for digital circuitry on chip. Supplied by the on-
chip regulator unless configured for regulator off mode using the
LED1/REGOFF pin. A 1uF decoupling capacitor to ground should be used on
this pin when using the internal 1.2V regulator.

P
+3.3V Analog Port Power to Channel 2 and to internal regulator.
VSS
FLAG
GND
The flag must be connected to the ground plane with a via array under the
exposed flag. This is the ground connection for the IC.
