MAX115EAX

2X4通道，同时采样12位ADC 2x4-Channel, Simultaneous-Sampling 12-Bit ADCs

General Description

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.
