KAD5612P-21Q72

Analog To Digital Converters (ADC) Overview

The KAD5612P-21Q72 is a dual-channel, 12-bit analog-to-digital converter (ADC) from the KAD5612P family. It operates at a sampling rate of 210 MSPS and utilizes a pipeline architecture with differential inputs. The device integrates an on-chip track-and-hold amplifier for each channel and supports selectable LVDS or CMOS digital output formats. Powered by Kenet’s FemtoCharge technology on a standard CMOS process, it achieves low power consumption while maintaining high performance. Key electrical specifications include a signal-to-noise ratio (SNR) of approximately 68 dBFS and a spurious-free dynamic range (SFDR) exceeding 80 dB. It is housed in a 72-contact QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'Q72' against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure compatibility with existing PCB footprints for the 72-contact QFN package. Confirm that the 210 MSPS sampling rate meets system bandwidth requirements. Validate power supply decoupling for both analog and digital domains as specified in the application notes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and 12-bit resolution are required at 210 MSPS. Compare against the KAD5610P-21 for 10-bit applications or the KAD5612P-25 if higher speed up to 250 MSPS is needed. Consider the SPI configurability for precise calibration needs. Evaluate power consumption constraints relative to the 1.8V supply requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the KAD5612P family of high-speed ADCs, which includes variants like the KAD5612P-25 (250 MSPS), KAD5612P-17 (170 MSPS), and KAD5612P-12 (125 MSPS). These devices share pin compatibility and architectural features, allowing for design flexibility across different speed requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the KAD5612P-25Q72, KAD5612P-17Q72, and KAD5612P-12Q72. Verify that the alternative's sampling rate and power consumption align with the original design specifications before substitution.
