The ISLA112P25MREP is a low-power 12-bit, 250MSPS

analog-to-digital converter. Designed with Intersil’s

proprietary FemtoCharge? technology on a standard

CMOS process.

A serial peripheral interface (SPI) port allows for

extensive configurability, as well as fine control of various

parameters such as gain and offset.

Digital output data is presented in selectable LVDS or

CMOS formats. The ISLA112P25MREP is available in a

72 Ld QFN package with an exposed paddle. Operating

from a 1.8V supply, performance is specified over the full

military temperature range (-55°C to +125°C).
