Maxim Integrated Products has introduced what it says is the industry's smallest 2-channel ADC.
The MAX11645 12-bit I2C ADC includes an internal reference in a tiny 1.9mm x 2.2mm wafer-level package (WLP). A 4 x 3 bump array with 0.5mm pitch facilitates layout on four-layer PCBs, while a slim 0.64mm height makes it well-suited for designs laying components out on both sides of the PCB. Applications range from energy-harvesting sensors, to portable consumer electronics, to point-of-load monitoring (voltage, current, and temperature) in networking and computer systems.

If it is to be employed with uC, why not use uC with integrated ADC? What are typical applications for this implementation?
If it is to be used, it needs additional analog signal conditioning. Can they include some of them in this type of tiny chip to make system real compact?
