MAX188BCWP+

The MAX188BCWP+ is a low power, 8 channel, serial 12bit analogue to digital converter in 20 pin WSOIC package. It is a 12bit data acquisition system that combines an 8 channel multiplexer, high bandwidth track/hold and serial interface together with high conversion speed and ultralow power consumption. 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 digital signal processors. It uses either the internal clock or an external serial interface clock to perform successive approximation A/D conversions. The serial interface can operate beyond 4MHz when internal clock is used. It provides a hard wired active-low SHDN pin and two software selectable power down modes. It is used in portable data logging, data acquisition, high accuracy process control, automatic testing, robotics, battery powered instruments and medical instruments.
