Featuring independent track and hold (T/H) and SAR circuitry, these parts provide simultaneous sampling at 250ksps for each channel. The MAX11047/MAX11048/MAX11049 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, 16-bit, bidirectional, parallel interface provides the conversion results and accepts digital configuration inputs. The MAX11047/MAX11048/MAX11049 operate with a 4.75V to 5.25V analog supply and a separate flex...
