Overview
The ISLA212P50IRZ is a high-performance 12-bit, 500MSPS analog-to-digital converter (ADC) designed by Renesas Electronics America Inc. This device is built using Intersil's proprietary FemtoCharge™ technology on a standard CMOS process. It is part of a pin-compatible portfolio of 12 to 16-bit ADCs with sample rates ranging from 130MSPS to 500MSPS. The ISLA212P50IRZ utilizes two time-interleaved 250MSPS unit ADCs to achieve its high sample rate, with internal management of interleave clocking and automatic correction of offset, gain, and sample time mismatches through the Intersil Interleave Engine (I2E).
