The KAD5510P-50 is a low-power, high performance, 10-bit, 500MSPS analog-to-digital converter designed with Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process. The KAD5510P-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 10-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 KAD5510P-50 is available in a 72 Ld QFN package with an exposed paddle. Performance is specified over the full industrial temperature range (-40°C to +85°C).
