Analog Devices MAX11047, MAX11048, and MAX11049 analog-to-digital converters are 16-bit, up-to-8-channel, simultaneous-sampling SAR ADCs. The MAX11047 offers up to four independent input channels, the MAX11048 offers six, and the MAX11049 has eight. These Analog Devices ADCs feature independent track and hold (T/H) and SAR circuitry and provide simultaneous sampling at 250ksps for each channel. These 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.
