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).
