KAD5514P
FN6804.2
14-Bit, 250/210/170/125MSPS ADC
The KAD5514P is a family of low-power, high-performance
14-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 KAD5514P is part of a pin-compatible
portfolio of 10, 12 and 14-bit A/Ds with sample rates ranging
from 125MSPS 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. The KAD5514P is available in 72- and 48-contact
QFN packages with an exposed paddle. Operating from a
1.8V supply, performance is specified over the full industrial
temperature range (-40°C to +85°C).
