MAX11140ATI+ General Description

The MAX11135–MAX11143 are 12-/10-/8-bit with external reference and industry-leading 1.5MHz, full linear bandwidth, high speed, low-power, serial output successive-approximation register (SAR) analog-to-digital converters (ADCs). The MAX11135–MAX11143 include both internal and external clock modes. These devices feature scan mode in both internal and external clock modes. The internal clock mode features internal averaging to increase SNR. The external clock mode features the SampleSet™ technology, a user-programmable analog input channel sequencer. The SampleSet approach provides greater sequencing flexibility for multichannel applications while alleviating significant microcontroller or DSP (controlling unit) communication overhead.
