MAX11101
14-Bit, +5V, 200ksps ADC with 10µA Shutdown
General Description
The MAX11101 low-power, 14-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 MAX11101 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 MAX11101
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^M and 12-bump WLP), make the MAX11101 ideal
for battery-powered and data-acquisition applications
or for other circuits with demanding power consumption
and space requirements.
