Description

Create a design and simulate using EE-Sim^® tools:

The MAX11101 low-power, 14-bit analog-to-digital converter (ADC) features a successive approximation ADC, automatic power-down, fast 1.1µs wake-up, and a high-speed SPI/QSPI™/MICROWIRE®-compatible interface. The MAX11101 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 MAX11101 consumes typically 2.45mA. Power consumption is typically 12.25mW (V_AVDD = V_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 12-bump WLP), make the MAX11101 ideal for battery-powered and data-acquisition applications or for other circuits with demanding power consumption and space requirements.
