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 bothfast and high-speed modes.The MAX1169 operates from a single supply and consumes5mW at the maximum conversion rate of58.6ksps. AutoShutdown™ powers down the devicebetween conversions, reducing supply current to lessthan 50μA at a 1ksps throughput rate. The opTIon of aseparate digital supply voltage allows direct interfacingwith +2.7V to +5.5V digital logic.The MAX1169 performs a unipolar conversion on itssingle analog input using its internal 4MHz clock. Thefull-scale analog input range is determined by the internalreference or by an externally applied reference voltageranging from 1V to AVDD.The four address select inputs (ADD0 to ADD3) allowup to 16 MAX1169 devices on the same bus.The MAX1169 is packaged in a 14-pin TSSOP and offers both commercial and extended temperature ranges. Refer to the MAX1069 data sheet for a 14-bit device in a pin-compatible package.
