KAD5512HP-25Q72

Analog To Digital Converters (ADC) Overview

The KAD5512HP-25Q72 is a high-performance, single-channel 12-bit analog-to-digital converter (ADC) manufactured by Renesas Electronics. It operates at a maximum sampling rate of 250MSPS and utilizes Intersil’s proprietary FemtoCharge technology on a standard CMOS process. The device features a 950MHz analog input bandwidth and supports selectable LVDS or LVCMOS digital output formats. It functions from a single 1.8V supply and is housed in a 72-lead HVQCCN package with an exposed paddle.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix Q72 to confirm the 72-lead QFN package configuration. Ensure the component meets RoHS compliance standards as indicated by Pb-free manufacturing processes. Confirm that the operating temperature range aligns with industrial specifications (-40°C to +85°C). Validate the datasheet revision against the latest Renesas documentation to ensure accuracy of electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution and 250MSPS sampling rate are required within the KAD5512 family. Consider the HP variant for superior Signal-to-Noise Ratio (SNR) compared to standard versions. Evaluate power consumption requirements across SDR and DDR modes. Ensure the system design accommodates the 1.8V single-supply operation and appropriate clock jitter specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the KAD5512 family of high-speed ADCs, which includes 10, 12, and 14-bit variants. The HP designation indicates a high-performance version optimized for better dynamic performance metrics like SNR and SFDR. It shares pin compatibility with other members of the series, facilitating upgrades or downgrades in existing designs without PCB modifications.

Analog To Digital Converters (ADC) Replacement Considerations

No recommended replacements are available as the part is marked NRND (Not Recommended for New Designs). Existing designs should continue using this component until end-of-life. Alternative solutions require a full redesign due to the lack of a direct pin-compatible substitute.
