58.6ksps, 16-Bit,
2-Wire Serial ADC in a 14-Pin TSSOP19-2654; Rev 2; 12/10
General DescriptionThe 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
I2C-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 VAVDD.
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
operates over an extended temperature range. Refer to
the MAX1069 data sheet for a 14-bit device in a pin-
compatible package.

Note 1:DC accuracy is tested at VAVDD= +5.0V and VDVDD= +3.0V. Performance at power-supply tolerance limits is guaranteed
by power-supply rejection test.
Note 2:Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offset have been calibrated.
Note 3:Offset nullified.
Note 4:One sample is achieved every 18 clocks in continuous conversion mode:
Note 5:The track/hold acquisition time is two SCL cycles as illustrated in Figure 11:
Note 6:A filter on SDA and SCL delays the sampling instant and suppresses noise spikes less than 10ns in high-speed mode and
50ns in fast mode.
Note 7:ADC performance is limited by the converter’s noise floor, typically 225µVP-P.
