MAX1062_09 Datasheet, PDF (1/18 Pages) Maxim Integrated Products – 14-Bit, +5V, 200ksps ADC with 10μA Shutdown

19-2203; Rev 1; 5/09
14-Bit, +5V, 200ksps ADC with 10µA Shutdown
General Description
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_DD = DV_DD = 5V) at
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^®) make the MAX1062 ideal for battery-powered
and data-acquisition applications or for other circuits
with demanding power consumption and space
requirements.
