Maxim Integrated Products has introduced what it says is the industry's smallest 2-channel ADC .

The MAX11645 12-bit I² C 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.
