Overview
The ISLA112P50IRZ is a high-performance, low-power analog-to-digital converter (ADC) produced by Renesas Electronics America Inc. This 12-bit ADC operates at a sampling rate of 500 million samples per second (MSPS) and is designed using Intersil's proprietary FemtoCharge™ technology on a standard CMOS process. It is part of a pin-compatible portfolio that includes 8, 10, and 12-bit ADCs, making it an upgrade to the KAD551XP-50 product family. The device achieves its high sampling rate through two time-interleaved 250MSPS unit ADCs, with internal management of interleave clocking and automatic fine correction of offset, gain, and sample time skew mismatches using the Intersil Interleave Engine (I2E).
