MAX1069
58.6ksps, 14-Bit, 2-Wire Serial ADC
in a 14-Pin TSSOP19-2652; Rev 0; 10/02
General DescriptionThe 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 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 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 inter-
nal reference or by an externally applied reference volt-
age ranging from 1V to AVDD.
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.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:DC accuracy is tested at AVDD= +5.0V and DVDD= +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 480µVP-P.
Note 8:

Note 9:A master device must provide a data hold time for SDA (referred to VILof SCL) in order to bridge the undefined region of
SCL’s falling edge (see Figure 1).
Note 10:CB= total capacitance of one bus line in pF. tRand tFmeasured between 0.3 ✕DVDDand 0.7 ✕DVDD.
Note 11:fSCLmust meet the minimum clock low time plus the rise/fall times.
