The KAD5512P-50 is a low-power, high-performance, 12-bit,
500MSPS analog-to-digital converter designed with Intersil’s
proprietary FemtoCharge? technology on a standard
CMOS process. The KAD5512P-50 is part of a
pin-compatible portfolio of 10, 12 and 14-bit A/Ds with
sample rates ranging from 125MSPS to 500MSPS.
The device utilizes two time-interleaved 12-bit, 250MSPS
A/D cores to achieve the ultimate sample rate of 500MSPS.
A single 500MHz conversion clock is presented to the
converter, and all interleave clocking is managed internally.
A serial peripheral interface (SPI) port allows for extensive
configurability, as well as fine control of matching
characteristics (gain, offset, skew) between the two
converter cores. These adjustments allow the user to
minimize spurs associated with the interleaving process.
Digital output data is presented in selectable LVDS or CMOS
formats. The KAD5512P-50 is available in a 72-contact QFN
package with an exposed paddle. Performance is specified
over the full industrial temperature range (-40°C to +85°C).
