Low Power 10-Bit, 250/210/170/125MSPS ADC
KAD5510P
The KAD5510P is a family of low power, high performance 10-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
KAD5510P 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 KAD5510P is available in a 48-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).
