Overview
The KAD5512P-50, also known as KAD5512P-12Q72, is a high-performance, 12-bit analog-to-digital converter (ADC) produced by Renesas Electronics America Inc. This device is designed using Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process, offering low power consumption and high-speed conversion capabilities. It is part of a pin-compatible portfolio of ADCs with sample rates ranging from 125MSPS to 500MSPS. The KAD5512P-50 achieves a sample rate of 500MSPS through two time-interleaved 12-bit, 250MSPS A/D cores, with all interleave clocking managed internally. The device is available in a 72-lead QFN package with an exposed paddle and operates across the full industrial temperature range (-40°C to +85°C).
