14-Bit, +5V, 200ksps ADC with 10µA Shutdown
General Description
Features
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.
ꢀ 14-Bit Resolution, 1LSB DNL
ꢀ +5V Single-Supply Operation
ꢀ Adjustable Logic Level (2.7V to 5.25V)
ꢀ Input Voltage Range: 0 to V

ꢀ Internal Track/Hold, 4MHz Input Bandwidth
ꢀ SPI/QSPI/MICROWIRE-Compatible Serial Interface
ꢀ Small 10-Pin µMAX Package
At the maximum sampling rate of 200ksps, the
MAX1062 consumes only 2.5mA. Power consumption is
only 12.5mW (AV

sampling rate. AutoShutdown™ reduces supply current
to 130µA 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.
