MAX11047

The max11047/max11048/max11049 and max11057/ max11058/max11059 16-bit/14-bit adcs offer 4, 6, or 8 independent input channels. featuring independent track and hold (t/h)and sar circuitry, these parts provide simultaneous sampling at 250ksps for each channel. the max11047/max11048/max11049 are available in a 56-pin tqfn and 64-pin tqfp packages while the max11057/ max11058/max11059 are available in tqfp only. 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. all devices operate over the extended -40°c to +85°c temperature range. 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 accept a 0 to +5v input. all inputs are overrange protected with internal ±20ma input clamps providing overrange protection with a simple external resistor.
