|
|
RBIAS | 32 | 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. |

VDDIO | 12 | P | +1.6V to +3.6V Variable I/O Pad Power | |
|
|
|
|
|
VDDCR | 6 | 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. | |
|
|
|
|
|
VDD1A | 27 | P | +3.3V | Analog Port Power to Channel 1. |
|
|
|
|
|
VDD2A | 1 | 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. | |
