MAX11102AUB+

The MAX11102/MAX11103/MAX11105/MAX11106/ MAX11110/MAX11111/MAX11115/MAX11116/ MAX11117 are 12-/10-/8-bit, compact, high-speed, lowpower, successive approximation analog-to-digital converters (ADCs). These high-performance ADCs include a high-dynamic range sample-and-hold and a high-speed serial interface. These ADCs accept a full-scale input from 0V to the power supply or to the reference voltage. The MAX11102/MAX11103/MAX11106/MAX11111 feature dual, single-ended analog inputs connected to the ADC core using a 2:1 MUX. The devices also include a separate supply input for data interface and a dedicated input for reference voltage. In contrast, the single-channel devices generate the reference voltage internally from the power supply. These ADCs operate from a 2.2V to 3.6V supply and consume only 3.7mW at 2Msps and 5.2mW at 3Msps. The devices include full power-down mode and fast wake-up for optimal power management and a highspeed 3-wire serial interface. The 3-wire serial interface directly connects to SPI, QSPIK, and MICROWIRE devices without external logic. Excellent dynamic performance, low voltage, low power, ease of use, and small package size make these converters ideal for portable battery-powered data-acquisition applications, and for other applications that demand low-power consumption and minimal space.
