ADP0001 I2C Adapter Output Voltage Higher Than Configured Setting

[pkokoras]

I have just received an I2C Adapter Phidget (SKU: ADP0001_0). After opening the Phidget Control Panel, I set the configuration voltage to 5 V. I then connected the ground probe of my multimeter to the GND pin on the ADP0001 and the positive probe to VCC. The measured voltage was 6.87 V.

When I changed the configuration voltage to 3.3 V, the multimeter read 4.53 V. When set to 2.5 V, the measured voltage was 3.45 V.

Are these measurements expected, or could this indicate a configuration or hardware issue?

Thanks, Panayiotis
