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 Ld QFN packages with an exposed paddle. Operating from a 1. 8V supply, performance is specified across the full industrial temperature range (-40°C to +85°C).
