The MAX115/MAX116 are high-speed, multichannel, 12-bit data-acquisition systems (DAS) with simultaneous track/holds (T/Hs). These devices contain a 12-bit, 2µs, successive-approximation analog-to-digital converter (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 damage 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 microprocessors. The MAX115/MAX116 conversion results can be accessed without resorting to wait-states.
