KAD5512HP
FN6808.3
High Performance 12-Bit,
250/210/170/125MSPS ADC
The KAD5512HP is the high-performance member of the
KAD5512 family of 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 KAD5512HP 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 KAD5512HP 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).
