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 analogsupply 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 only 12.5mW (AV_DD = DV_DD = +5V) at a 200ksps (max) 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.
