The MAX11190 is a 4-channel, dual, multiplexed, 12-bit, compact, high-speed, low-power, successive approximation analogue-to-digital converter (ADC), that includes high-dynamic range sample-and-holds and a high-speed serial interface. This ADC accepts a full-scale input from 0V to the reference voltage.
The device features two dual, single-ended analogue inputs connected to two ADC cores using 2:1 MUXs. The device also includes a separate supply input for data interface and dedicated inputs for reference voltage. It is low-noise, with 72dB SNR.
This device operates from a 2.2V to 3.6V supply and consumes 10.5mW at 3 Msamples/sec. It includes full power-down mode and fast wake-up for optimal power management and a high-speed 3-wire serial interface. The 3-wire serial interface directly connects to SPI, QSPI, and MICROWIRE devices without external logic. Each of the two internal ADCs has its own dedicated DOUTA/DOUTB for faster data communication.
Dynamic performance, low voltage, low power, ease of use, and small package size suit this converter to simultaneous data-acquisition applications, and for other applications that demand low power consumption and minimal space. It operates over the -40°C to +125°C temperature range.
