KAD5512HP-12Q72

Analog To Digital Converters (ADC) Overview

The KAD5512HP-12Q72 is a single-channel, 12-bit analog-to-digital converter (ADC) from the Renesas KAD5512 family. It supports sampling rates up to 125 MSPS and features a 950 MHz analog input bandwidth with 60 fs clock jitter. The device operates on a single 1.8V supply and offers selectable DDR LVDS-compatible or LVCMOS digital outputs. Key performance metrics include an SNR of 68.2 dBFS and SFDR of 81.1 dBc at 105 MHz input frequency. Power consumption ranges from 309 mW to 429 mW depending on the mode and speed. It utilizes Intersil’s FemtoCharge technology and includes programmable gain, offset, and skew controls via an SPI interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors as this part is marked NRND. Confirm package integrity for the 72-lead QFN variant. Check RoHS compliance status for environmental regulations. Ensure design-in compatibility with existing pin layouts due to its legacy status. Validate supply chain stability given the lack of recommended replacements.

Analog To Digital Converters (ADC) Selection Notes

Select this component only if pin compatibility with the KAD5512P family is required. Consider the 1.8V single-supply operation for low-power designs. Evaluate the 950 MHz bandwidth against specific input signal frequencies. Review the available output formats to match downstream digital logic requirements. Assess power consumption limits in both SDR and DDR modes for thermal management.

Analog To Digital Converters (ADC) Part Context

This ADC belongs to the KAD5512 family, which includes 10, 12, and 14-bit variants with sample rates from 125 MSPS to 500 MSPS. The HP series represents the high-performance member of this portfolio.
