ISLA222P25

Dual 12-Bit, 250MSPS ADC

Product Status: 量産中

OVERVIEW

The ISLA222P is a family of dual-channel 12-bit analog-to-digital converters. Designed with Intersil's proprietary FemtoCharge™ technology on a standard CMOS process, the family supports sampling rates of up to 250MSPS. The ISLA222P is part of a pin-compatible portfolio of 12-bit and 14-bit dual-channel A/Ds with maximum sample rates ranging from 130MSPS to 250MSPS.

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 ISLA222P is available in a 72 lead QFN package with an exposed paddle. Operating from a 1.8V supply, performance is specified over the full industrial temperature range (-40°C to +85°C).
