Аналого-цифровые преобразователи (АЦП) MAX11131ATI+

АЦП , 12 бит, 3 Мвыборок/с, Дифференциальный, Псевдо-дифференциальный, Несимметричный, SPI

The MAX11131ATI+ from Maxim Integrated Products is a 3Msps, low power, serial 12bit, 16-channel analogue to digital converter (ADC) in 28 pin TQFN package. This device with external reference and industry leading 1.5MHz, full linear bandwidth, high speed and serial output successive approximation register (SAR) ADC. It includes both internal and external clock modes, devices feature scan mode in both internal, external clock modes. The internal clock mode has internal averaging to increase SNR. The external clock mode has SampleSet™ technology, user programmable analogue input channel sequencer. Excellent dynamic performance, low voltage, low power, ease of use and small package makes this IC ideal for portable battery powered, data acquisition applications and for other applications that demand low power consumption and small space. Applications include high speed closed loop system, industrial control systems, medical instrumentation, battery powered instruments.
