The MAX1162 low-power, 16-bit analog-to-digital con-
verter (ADC) features a successive-approximation ADC,
automatic power-down, fast 1.1µs wakeup, and a high-
speed SPI™/QSPI™/MICROWIRE™-compatible inter-
face. The MAX1162 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
MAX1162 consumes typically 2.75mA. Power con-
sumption is typically 13.75mA (AV
a 200ksps (max) sampling rate. AutoShutdown™
reduces supply current to 140µA at 10ksps and to less
than 10µA at reduced sampling rates.
Excellent dynamic performance and low power, com-
bined with ease of use and small package size (10-pin

battery-powered and data-acquisition applications or
for other circuits with demanding power consumption
and space requirements.
