Methods and devices for code independent switching in signal processing circuit such as a digital-to-analog converter (DAC) are described, which provide code independent switching activity. A steering cell receives a digital data input signal that is defined at data intervals, and produces multiple representative analog output signals. For each data interval, each analog output signal depends only on the present state of the digital data input signal, independently of any previous state of the digital data input signal. In addition, the signal processing circuit apart from the analog output signals is substantially free of data dependent disturbances.
