_______________Detailed Description
The MAX115/MAX116 use a successive-approximation
conversion technique and four simultaneous-sampling
track/hold (T/H) amplifiers to convert analog signals into
12-bit digital outputs. Each T/H has two multiplexed
inputs, allowing a total of eight inputs. Each T/H output
is converted and stored in memory to be accessed
sequentially by the parallel interface with successive
read cycles. The MAX115/MAX116 internal micro-
sequencer can be programmed to digitize one, two,
three, or four inputs sampled simultaneously from either
of the two banks of four inputs (Figure 2). The
MAX115/MAX116 can operate with either an external or
internal clock. For internal operation, connect CLK to
DV
DD
