MAX1069

The MAX1069 is a low-power, 14-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 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 AVDD.

The four address select inputs (ADD0ADD3) 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.
