Overview
The KAD5514P-25Q72 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 includes ADCs with sampling rates ranging from 125MSPS to 250MSPS. The KAD5514P-25Q72 is designed using Renesas' proprietary FemtoCharge™ technology on a standard CMOS process, ensuring low power consumption and high performance. It features a single-channel, differential input and supports both LVDS and LVCMOS output formats. The device is highly configurable via a Serial Peripheral Interface (SPI) port, allowing for fine control over parameters such as gain and offset. It operates from a single 1.8V supply and is specified across the full industrial temperature range of -40°C to +85°C.
