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 AVDD.
The four address select inputs (ADD0 to ADD3) allow
up 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.
