An analog-to-digital converter including a first stage and a second stage. The first stage includes a first sample-and-hold (SH) having an input coupled to a voltage input node of the ADC, and having a first SH output. The first stage also includes a buffer, a first flash converter and a first digital-to-analog converter (DAC). The buffer has an input coupled to the first SH output and has a buffer output. The first flash converter has an input coupled to the first SH output, and has a first flash converter output. The first DAC has an input coupled to the first flash converter output. The second stage includes a second flash converter having an input coupled to the buffer output.
