MAX188

EVALUATION KIT AVAILABLE MAX186/MAX188 Low-Power, 8-Channel, Serial 12-Bit ADCs General Description The MAX186/MAX188 are 12-bit data-acquisition systems that combine an 8-channel multiplexer, highbandwidth 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 analog 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/MAX188 use either the internal clock or an external serial-interface clock to perform successiveapproximation A/D conversions. The serial interface can operate beyond 4MHz when the internal clock is used. The MAX186 has an internal 4.096V reference while the MAX188 requires an external reference. Both...
