The MAX1246/MAX1247 12-bit data-acquisition systems combine a 4-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption. The MAX1246 oper ates from a single +2.7V to +3.6V supply; the MAX1247 operates from a single +2.7V to +5.25V supply. Both devices’ analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation.The 4-wire serial interface connects directly to SPI? QSPI? and Microwire? devices without external logic. A serial strobe output allows direct connection to TMS320 family digital signal processors. The MAX1246/MAX1247 use either the internal clock or an external serial-interface clock to perform successive-approximation analog-to-digital conversions.The MAX1246 has an internal 2.5V reference, while the MAX1247 requires an external reference. Both parts have a reference-buffer amplifier with a ±1.5% voltage-adjustment range.
