MAX11128ATI+

The MAX11128ATI+ is a 1Msps, low-power, serial 12bit, 16 channel ADC in 28 pin TQFN-EP package. This 12bit ADC with external reference and industry-leading 1.5MHz, full linear bandwidth, high speed, low-power, serial output SAR ADC. It includes both internal and external clock modes. This device features 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 analogue input channel sequencer. The SampleSet approach provides greater sequencing flexibility for multichannel applications while alleviating significant microcontroller or DSP 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.
