Аналого-цифровые преобразователи (АЦП) MAX188DCWP+

АЦП , 12 бит, 133 Квыборок/с, Дифференциальный, Псевдо-дифференциальный, Несимметричный, SPI

The MAX188DCWP+ from Maxim Integrated Products is a low power, 8 channel, serial 12bit analogue to digital converter in 20 pin WSOIC package. This data acquisition system combines an 8 channel multiplexer, high bandwidth track/hold and serial interface together with high conversion speed and ultra low power consumption. The analogue inputs are software configurable for unipolar/bipolar and single ended/differential operation. The 4 wire serial interface directly connects to SPI, QSPI and MICROWIRE devices without external logic. A serial strobe output allows direct connection to TMS320 family DSP. It uses an external serial interface clock to perform successive approximation A/D conversions. The serial interface can operate beyond 4MHz when the internal clock is used. Typically used at portable data logging, data acquisition, high-accuracy process control, automatic testing, robotics, battery-powered instruments and medical instruments.
