P1-P3P4-P6P7-P9P10-P12P13-P14
________________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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
