KAD5514P-17

14-Bit, 170MSPS Single-Channel ADC with LVDS/LVCMOS Outputs

Product Status: Mass Production

OVERVIEW

The KAD5514P is a family of low-power, high performance 14-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 KAD5514P 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 KAD5514P is available in 72 Ld 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).
