14-Bit, 250MSPS/200MSPS/130MSPS ADC

ISLA214P

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).
