MAX11047–MAX11049/MAX11057–MAX11059 19-5106; Rev 2; 1/11 EVAALVUAAILTAIOBNLEKIT 4-/6-/8-Channel, 16-/14-Bit, Simultaneous-Sampling ADCs General Description 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 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. 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. The MAX11047/MAX11048/M...
