Systems, methods, and devices for data converter management
Systems, methods, and devices enhance management of components used in data converters. Methods include receiving an input at a data converter comprising a digital to analog converter (DAC), the digital to analog converter comprising a plurality of sensing elements, and performing, using the DAC, a first conversion operation based on the input and a first set of the plurality of sensing elements identified by a first pointer value. Methods also include determining a pointer increment value based, at least in part, on an output of the first conversion operation and a hysteresis threshold value, the pointer increment value being used to determine an amount by which the first pointer value is incremented, the hysteresis threshold value identifying a threshold for determination of the pointer increment value.
