Abstract

An ultrasound probe analog to digital converter includes an input successive approximation register (SAR) first stage; and an output SAR second stage in communication with the input SAR first stage. The input SAR first stage includes a programmable preamplifier integrated therein for residue amplification. The preamplifier is programmed to alternate between a linear amplifier operating mode and a comparator operating mode.
