MAX1169

MAX1169 19-2654; Rev 2; 12/10 EVAALVUAAILTAIOBNLEKIT 58.6ksps, 16-Bit, 2-Wire Serial ADC in a 14-Pin TSSOP General Description The MAX1169 is a low-power, 16-bit successiveapproximation analog-to-digital converter (ADC). The device features automatic power-down, an on-chip 4MHz clock, a +4.096V internal reference, and an I2C-compatible 2-wire serial interface capable of both fast and high-speed modes. The MAX1169 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 50µA 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 MAX1169 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. Th...
