MAX11100 Analog-to-Digital Converter

MAX11100 Analog-to-Digital Converter

Maxim's MAX11100 low-power, 16-bit analog-to-digital converter (ADC) features a successive-approximation ADC, automatic power-down, fast 1.1 µs wake-up, and a high-speed SPI/QSPI™/MICROWIRE®-compatible interface. The MAX11000 operates with a single +5 V analog supply and features a separate digital supply, allowing direct interfacing with 2.7 V to 5.25 V digital logic. At the maximum sampling rate of 200 ksps, the MAX11100 typically consumes 2.45 mA. Power consumption is typically 12.25 mW (VAVDD = VDVDD = +5 V) at a 200 ksps (max) sampling rate. AutoShutdown™ reduces supply current to 140 µA at 10 ksps and to less than 10 µA at reduced sampling rates. Excellent dynamic performance and low power, combined with ease of use and small package size (10-pin µMAX® and 12-bump WLP), make the MAX11100 ideal for battery-powered and data-acquisition applications or for other circuits with demanding power consumption and space requirements.
