When alternate bit polarity mode is enabled, all of the odd bits (D1, D3, D5, D7, D9, D11, D13) are inverted before the output buffers. The even bits are not affected. This method helps reduce digital currents in the circuit board ground plane that cause digital noise, particularly for very small analog input signals. The digital output can be decoded at the receiver by inverting the odd bits. The optional alternate bit polarity mode is enabled via serial programming.
