KAD5512P-12Q72

Analog To Digital Converters (ADC) Overview

The KAD5512P-12Q72 is a single-channel, 12-bit analog-to-digital converter (ADC) from the KAD5512 family. It supports sampling rates up to 125 MSPS and features an analog input bandwidth of 950 MHz. The device operates on a single 1.8 V supply and utilizes FemtoCharge technology for low power consumption. Key electrical parameters include a Signal-to-Noise Ratio (SNR) of 68.2 dBFS at -1 dBFS input level and a Spurious-Free Dynamic Range (SFDR) of 81.1 dBc. It offers programmable gain, offset, and skew control via an SPI interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment before installation. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific suffix matches the required pin count and thermal pad configuration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution with 125 MSPS throughput is required in a 72-pin QFN package. Consider the KAD5512HP variant if higher SNR performance is needed, noting it may have different power characteristics. Ensure the design accommodates the 1.8 V single-supply requirement and LVDS/LVCMOS output voltage levels.

Analog To Digital Converters (ADC) Part Context

This component belongs to the KAD5512 family of high-speed ADCs designed with Intersil’s proprietary FemtoCharge technology. The family includes pin-compatible 10, 12, and 14-bit variants with sampling rates ranging from 125 MSPS to 500 MSPS. The KAD5512P-12Q72 specifically denotes the 12-bit version in a 72-lead QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

No recommended replacements are available as the part is not recommended for new designs. Potential substitutes within the same family include KAD5512P-12Q48 (48-lead QFN) or KAD5512HP-12 series for enhanced performance, though pin compatibility must be verified.
