Overview
The KAD5514P-25Q48 is a high-performance, 14-bit analog-to-digital converter (ADC) produced by Renesas Electronics America Inc. This device is part of the KAD5514P family, which is designed using the proprietary FemtoCharge™ technology on a standard CMOS process. It supports sampling rates of up to 250 million samples per second (MSPS) and is known for its low power consumption and high accuracy. The KAD5514P-25Q48 is available in a 48-lead QFN package with an exposed paddle and operates from a single 1.8V supply, making it suitable for a wide range of applications across the full industrial temperature range (-40°C to +85°C).
