    Voltage Reference not on chip

    robert.seczkowski
              I've created circuit consisting of: 1. op-amp follower 2. voltage reference 3. analog pin P0_1 4. External resistor 20K on P0_1 to Power GND Voltage measured on P0_1 regardless of Vref configuration (1.024 nor 0.256V) is always 1.811V When set to Vdd/2 output is 3.3/2 regards robert
