The MAX1062 low-power, 14-bit analog-to-digital con-
verter (ADC) features a successive approximation ADC,
automatic power-down, fast 1.1µs wake-up, and a high-
speed SPI™/QSPI™/MICROWIRE™-compatible inter-
face. The MAX1062 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
MAX1062 consumes typically 2.75mA. Power con-
sumption is typically 13.75mW (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
µMAX
and data-acquisition applications or for other circuits
with demanding power consumption and space
requirements.
