KAD5512HP-25Q48

Analog To Digital Converters (ADC) Overview

The KAD5512HP-25Q48 is a high-performance, single-channel 12-bit analog-to-digital converter (ADC) manufactured by Renesas Electronics. It utilizes Intersil’s proprietary FemtoCharge technology on a standard CMOS process to achieve sampling rates up to 250 MSPS. The device features a pipeline architecture with differential input and supports both LVDS and LVCMOS digital output formats via a parallel interface. It operates from a single 1.8 V supply for both analog and digital domains. Key performance specifications include an SNR of 68.8 dB at 105 MHz input frequency and a power consumption of 433 mW at 250 MSPS in SDR mode. The component is housed in a QFN-48 package and is rated for operation across the industrial temperature range of -40°C to +85°C.
