Provided are methods and systems for reducing a transition rate in transmitting data between analog and digital chips in Sigma-Delta Modulator (SDM) based Digital to Analog Converters (DACs) and Analog to Digital Converters (ADCs) intended to be used in audio signal processing. An example method may comprise receiving, by a digital chip, SDM binary data, mapping the SDM binary data to transition binary codes, and transmitting the transition binary codes to an analog chip. The mapping can be carried out according to a principle that the more commonly used SDM binary data codes correspond to transition binary data codes that require that fewer transitions occur in the signals between the chips. The methods and systems described provide for lowering the power needed for carrying out the data transmission between digital and analog chips.
