Notes

1.

Alternatively the common mode of the input can be set by applying different voltage sources to these two pins, in

2.

Digital input and output levels refer to the supply used for the input/output buffer on the relevant pin. CLK and MODE

refer to the AVDD supply, all other digital input/output refers to the DVDD supply.

3.

In full external reference mode the REFTF and REFTS pins should be shorted together, and the REFBF and REFBS

pins should be shorted together. Please refer to device operation examples in the device description section of the

datasheet.
