general description the MAX11612?ax11617 low-power, 12-bit, multi- channel analog-to-digital converters (adcs) feature internal track/hold (t/h), voltage reference, clock, and an i 2 c-compatible 2-wire serial interface. these devices operate from a single supply of 2.7v to 3.6v (max11613/max11615/max11617) or 4.5v to 5.5v (MAX11612/max11614/max11616) and require only 670? at the maximum sampling rate of 94.4ksps. supply current falls below 230? for sampling rates under 46ksps. autoshutdown powers down the devices between conversions, reducing supply current to less than 1? at low throughput rates. the MAX11612/max11613 have 4 analog input channels each, the max11614/max11615 have 8 analog input channels each, while the max11616/max11617 have 12 analog input channels each. the fully differential analog inputs are software configurable for unipolar or bipolar, and single-ended or differential operation. the full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1v to v dd . the max11613/ max11615/max11617 feature a 2.048v internal refer- ence and the MAX11612/max11614/max11616 feature a 4.096v internal reference. the MAX11612/max11613 are available in an 8-pin ?ax package. the max11614?ax11617 are avail- able in a 16-pin qsop package. the MAX11612 |
