Аналого-цифровые преобразователи (АЦП) MAX11337ATJ+

АЦП , 12 бит, 500 Квыборок/с, Дифференциальный, Несимметричный, SPI, Однополярный, 2.35 В

The MAX11337ATJ+ is a 12bit, 16-channel analogue to digital converter (ADC) with post-mux external signal conditioning access in 32 pin TQFN package. This is a high speed, low power, serial output successive approximation register (SAR) ADC with external reference and 500KHz full linear bandwidth. The MAX11337 provides external access to output of integrated mux and ADC input to simplify conditioning. It includes both internal and external clock modes. This device has scan mode in both internal and external clock modes. The internal clock mode features internal averaging to increase SNR. The external clock mode features SampleSetK technology and user programmable analogue input channel sequencer. The MAX11337 includes AutoShutdown, fast wake-up and high speed 3-wire serial interface. It has full power-down mode for optimal power management. The 8MHz, 3-wire serial interface directly connects to SPI, QSPI and MICROWIRE devices without external logic.
