Maxim Integrated MAX11048ECB

Description
The MAX11047/MAX11048/MAX11049 and MAX11057/MAX11058/MAX11059 are 16-bit/14-bit ADCs with 4, 6, or 8 independent input channels. They feature independent track-and-hold (T/H) and SAR circuitry, providing simultaneous sampling at 250ksps for each channel. The devices accept a 0 to 5V input and have internal 20mA input clamps for overrange protection. Other features include a 4MHz T/H input bandwidth, internal clock, and internal or external reference. A 20MHz, bidirectional, parallel interface provides the conversion results and accepts digital configuration inputs. The devices operate with a 4.75V to 5.25V analog supply and a separate flexible 2.7V to 5.25V digital supply for interfacing with the host without a level shifter.
