General Description

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 only 2.5mA. Power consumption is

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 and 10-pin DFN) make the MAX1162 ideal for

battery-powered and data-acquisition applications or

for other circuits with demanding power consumption

and space requirements.
