MAX186DCPP+ (MAXIM INTEGRATED PRODUCTS)

The MAX186DCPP+ is a 12-bit low-power Analogue-to-digital Converter for high-accuracy process control. The data-acquisition systems that combine an 8-channel multiplexer, high-bandwidth track/hold and serial interface together with high conversion speed and ultra-low power consumption. The devices operate with a single +5V supply or dual ±5V supplies. 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. The MAX186 use 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. The MAX186 provide a hard-wired active-low SHDN pin and two software-selectable power-down modes.
