_______________Detailed Description
Converter Operation
The MAX1294/MAX1296 ADCs use a successive-approx-
imation (SAR) conversion technique and an input
track/hold (T/H) stage to convert an analog input signal to
a 12-bit digital output. This output format provides easy
interface to standard microprocessors (Ps). Figure 2
shows the simplified internal architecture of the MAX1294/
MAX1296.
