MAX11100
16-Bit, +5V, 200ksps ADC with 10µA Shutdown
General Description
The MAX11100 low-power, 16-bit analog-to-digital con-
verter (ADC) features a successive-approximation ADC,
automatic power-down, fast 1.1Fs wake-up, and a high-
speed SPI/QSPI™/MICROWIRE®-compatible interface.
The MAX11100 operates with a single +5V analog supply
and features a separate digital supply, allowing direct
interfacing with 2.7V to 5.25V digital logic.
At the maximum sampling rate of 200ksps, the MAX11100
typically consumes 2.45mA. Power consumption is typi-
cally 12.25mW (V
AVDD
= V
DVDD
= +5V) at a 200ksps
(max) sampling rate. AutoShutdown™ reduces supply
current to 140FA at 10ksps and to less than 10FA at
reduced sampling rates.
Excellent dynamic performance and low power, com-
bined with ease of use and small package size (10-pin
FMAX
®
and 12-bump WLP), make the MAX11100 ideal
for battery-powered and data-acquisition applications
or for other circuits with demanding power consumption
and space requirements.

Note 1:
All WLP devices are 100% production tested at T
A
= +25NC. Specifications over temperature limits are guaranteed by
design and characterization.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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 3:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
Note 4:
Offset and reference errors nulled.
Note 5:
Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6:
Defined as the change in positive full scale caused by a
Q5%
variation in the nominal supply voltage.
