Product Details
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 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 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 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.
