GENERAL DESCRIPTION
The internal clock mode features internal averaging to increase SNR. The external clock mode features the SampleSetK 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. The internal clock mode features an integrated FIFO allowing data to be sampled at high speeds and then held for readout at any time or at a lower clock rate. Internal averaging is also supported in this mode improving SNR for noisy input signals. The devices feature analog input channels that can be configured to be single-ended inputs, fully differential pairs, or pseudo-differential inputs with respect to one common input. The MAX11135– MAX11143 operate from a 2.35V to 3.6V supply and consume only 4.2mW at 500ksps. The MAX11135–MAX11143 include AutoShutdownK, fast wake-up, and a high-speed 3-wire serial interface.
