High Performance Dual 14-Bit, 125MSPS ADC
ISLA224P12
The ISLA224P12 is a high performance dual 14-bit 125MSPS
analog-to-digital converter offering very high dynamic range and
low power consumption. It carries the export control
classification number 3A991.c.3 and can be exported without a
license to most countries, including China and Russia. It is part of
a pin-compatible family of 12- to 16-bit A/Ds with maximum
sample rates ranging from 125 to 500MSPS. This allows a design
using the ISLA224P12 to accommodate any of the other
pin-compatible A/Ds with minimal changes.
The ISLA224P12 is very flexible and can be designed into a wide
variety of systems. A serial peripheral interface (SPI) port allows
access to its extensive configurability as well as provides digital
control over various analog parameters such as input gain and
offset. Digital output data is presented in selectable LVDS or
CMOS formats in half-width, double data rate (DDR). Operating
from a 1.8V supply, performance is specified over the full
industrial temperature range (-40°C to +85°C).
