Аналого-цифровые преобразователи (АЦП) MAX11340ATJ+

АЦП , 10 бит, 500 Квыборок/с, Дифференциальный, Псевдо-дифференциальный, Несимметричный, SPI

The MAX11340ATJ+ from Maxim Integrated Products is a 10bit, 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 SAR ADC with external reference and 500KHz full linear bandwidth. The MAX11340 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 SampleSet™ technology and user programmable analogue input channel sequencer. The 8MHz, 3-wire serial interface directly connects to SPI, QSPI and MICROWIRE devices without external logic. It is used in high speed data, acquisition systems, high speed closed loop systems, industrial control systems, medical, battery powered instruments and portable systems.
