________________General Description
The MAX115/MAX116 are high-speed, multichannel,
12-bit data-acquisition systems (DAS) with simultane-
ous track/holds (T/Hs). These devices contain a 12-bit,
2μs, successive-approximation analog-to-digital con-
verter (ADC), a +2.5V reference, a buffered reference
input, and a bank of four simultaneous-sampling T/H
amplifiers that preserve the relative phase information
of the sampled inputs. The MAX115/MAX116 have two
multiplexed inputs for each T/H, allowing a total of eight
inputs. In addition, the converter is overvoltage tolerant
to ±17V. A fault condition on any channel will not dam-
age the IC. Available input ranges are ±5V (MAX115)
and ±2.5V (MAX116).
The parallel interface’s data access and bus release
timing specifications are compatible with most popular
digital signal processors and 16-bit/32-bit microproces-
sors. The MAX115/MAX116 conversion results can be
accessed without resorting to wait-states.
