Description

The MAX186, MAX186CEWP / MAX188 are 12-bit 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 consump tion. The devices operate with a single +5V supply or
dual ±5V supplies. The analog inputs are software configurable for unipolar/bipolar and single-ended/differen tial 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/MAX188 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.
