The MAX1162 low-power, 16-bit analog-to-digital converter (ADC) features a successive-approximation ADC, automatic power-down, fast 1.1µs wakeup, and a high-speed SPI/QSPI/MICROWIRE-compatible interface. 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 typically 2.75mA. Power consumption is typically 13.75mA (AVDD = DVDD = +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, combined 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.
