Analog Devices / Maxim Integrated MAX11321-28/MAX11335-40 12- & 10-bit ADCs

Analog Devices MAX11321-MAX11328 and MAX11335-MAX11340 12- and 10-bit multi-channel analog-to-digital converters (ADCs) feature external reference and 500kHz, full-linear-bandwidth, high-speed, low-power, serial-output successive approximation register (SAR). These ADI ADCs provide external access to the output of the integrated mux and ADC input to simplify conditioning. ADI MAX11321-28/MAX11335-40 12- and 10-bit ADCs include both internal and external clock modes. 

The 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 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 communication overhead. Analog Devices MAX11321-28/MAX11335-40 12- and 10-bit ADCs are ideal for use in battery-powered instruments, high-speed closed-loop systems, and more.
