Abstract: A device package includes a substrate having an active surface. Electrical connection bumps are deposited on the active surface and are arranged in an array having a perimeter. At least one electronic component is formed at a region of the active surface, where the region is located outside of the perimeter of the array of electrical connection bumps. When the device package is coupled with external circuitry via the electrical connection bumps, the region at which the electronic component is formed is suspended over the electronic circuitry. This region is subject to a lower stress profile than a region of the active surface circumscribed by the perimeter. Thus, stress sensitive electronic components can be located in this lower stress region of the active surface.

The fine ADC generates successive analog approximation signals for the analog input signal.

A controller controls operations of the sub-ranging ADC to correct for a detected coarse-ADC MTS condition. The MTS detection circuitry includes a positive MTS detector that detects a positive coarse-ADC MTS condition in the coarse ADC and a negative MTS detector that detects a negative coarse-ADC MTS condition in the coarse ADC.
