Overview
The ISLA224P20IRZ is a dual-channel 14-bit analog-to-digital converter (ADC) from Renesas Electronics America Inc. This component is part of the ISLA224P family, which is designed using Renesas' proprietary FemtoCharge™ technology on a standard CMOS process. The ISLA224P20IRZ supports a sampling rate of up to 200 million samples per second (MSPS). It is highly configurable through a serial peripheral interface (SPI) port, allowing fine control over parameters such as gain and offset. The ADC is available in a 72-contact QFN package with an exposed paddle and operates from a single 1.8V supply, ensuring performance across the full industrial temperature range (-40°C to +85°C).
