the max1069 is a low-power, 14-bit successive-approximation analog-to-digital converter (adc). the device features automatic power-down, an on-chip 4mhz clock, a +4.096v internal reference, and an ic-compatible 2-wire serial interface capable of both fast and high-speed modes. the max1069 operates from a single supply and consumes 5mw at the maximum conversion rate of 58.6ksps. autoshutdown powers down the device between conversions, reducing supply current to less than 50a at a 1ksps throughput rate. the option of a separate digital supply voltage allows direct interfacing with +2.7v to +5.5v digital logic. the max1069 performs a unipolar conversion on its single analog input using its internal 4mhz clock. the full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1v to vavdd. the four address select inputs (add0-add3) allow up to sixteen max1069 devices on the same bus. the max1069 is packaged in a 14-pin tssop and offers both commercial and extended temperature ranges. refer to the max1169 for a 16-bit device in a pin-compatible package.
