KAD5512HP-12Q48

Analog To Digital Converters (ADC) Overview

The KAD5512HP-12Q48 is a high-performance, single-channel 12-bit analog-to-digital converter (ADC) from the KAD5512 family. It utilizes Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process to support sampling rates up to 250MSPS, with this specific variant rated for 125MSPS. The device features a 950MHz analog input bandwidth and operates from a single 1.8V supply. Key electrical specifications include an SNR of 68.2dBFS at -1dBFS input level and an SFDR of 81.1dBc. It offers programmable gain, offset, and skew control via an SPI interface, with digital outputs available in DDR LVDS-compatible or LVCMOS formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify component status as the KAD5512HP series is marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors as stock may be limited. Ensure compliance with RoHS standards and check for moisture sensitivity levels prior to soldering. Review datasheet for handling precautions related to the QFN package.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high dynamic range is required over the standard KAD5512P variant. Ensure the design supports the 1.8V single-supply requirement and accommodates the QFN-48 package footprint. Verify that the host system can handle the selected output format (LVDS or LVCMOS) and clock frequencies up to 250MSPS if operating beyond the nominal 125MSPS rating.

Analog To Digital Converters (ADC) Part Context

This component belongs to the KAD5512 family of high-speed ADCs, which includes pin-compatible variants with resolutions of 10, 12, and 14 bits.
