General Description
The MAX1169 is a low-power, 16-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
I
2
C-compatible 2-wire serial interface capable of both
fast and high-speed modes.
The MAX1169 operates from a single supply and con-
sumes 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 inter-
nal reference or by an externally applied reference volt-
age ranging from 1V to AV
DD
.
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.
