Overview
The KAD5512P-17Q72 is a 12-bit analog-to-digital converter (ADC) from Renesas Electronics America Inc., part of the KAD5512 family. This device is designed using Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process, supporting sampling rates up to 170MSPS. It is part of a pin-compatible portfolio that includes 10, 12, and 14-bit ADCs with various sample rates. The KAD5512P-17Q72 features a Serial Peripheral Interface (SPI) for extensive configurability and control over parameters such as gain and offset. It operates from a single 1.8V supply and is specified over the full industrial temperature range (-40°C to +85°C).
