ISLA214P25

14-Bit, 250MSPS ADC

Product Status: Mass Production

OVERVIEW

The ISLA214P is a series of low power, high performance 14-bit analog-to-digital converters. Designed with Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process, the series supports sampling rates of up to 250MSPS. The ISLA214P is part of a pin-compatible family of 12 to 16-bit A/Ds with maximum sample rates ranging from 130MSPS to 500MSPS.

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, and can be configured as full-width, single data rate (SDR) or half-width, double data rate (DDR). The ISLA214P is available in a 72-contact 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).
