MAX186DEWP+ Datasheet PDF - Maxim Integrated

The MAX186DEWP+ 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 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 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 the internal clock is used. It provides a hard wired complementary SHDN pin and two software selectable power down modes.
