KAD5514P-25Q48

Analog To Digital Converters (ADC) Overview

The KAD5514P-25Q48 is a single-channel, 14-bit analog-to-digital converter (ADC) from the KAD5514P family. It features a pipeline architecture with a maximum sampling rate of 250 MS/s and an analog input bandwidth of 950 MHz. The device operates on a single 1.8 V supply and supports differential inputs. Digital outputs are available in selectable LVDS or LVCMOS formats. Key performance metrics include a Signal-to-Noise Ratio (SNR) of approximately 70.6 dB and a Spurious-Free Dynamic Range (SFDR) of 84.9 dB. It is housed in a 48-lead QFN package and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm RoHS compliance status as the part may be subject to end-of-life notices. Check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches the required package and temperature grade. Validate that the selected variant meets all electrical specifications for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 14-bit resolution and 250 MS/s sampling rate are required. Choose between LVDS or LVCMOS outputs based on system noise immunity and trace length constraints. Consider the 1.8 V single-supply operation for power-sensitive designs. Verify compatibility with existing clocking infrastructure given the 950 MHz input bandwidth requirement.

Analog To Digital Converters (ADC) Part Context

The KAD5514P-25Q48 belongs to the KAD5514P family of high-performance ADCs. This family includes variants with different sampling rates, such as the KAD5514P-12 (125 MSPS) and KAD5514P-17 (170 MSPS). All members share pin compatibility and similar architectural features, allowing for design flexibility across different speed requirements while maintaining software and hardware consistency.

Analog To Digital Converters (ADC) Replacement Considerations

Public documentation indicates that certain variants in the KAD5514P series may be marked as No Recommended Replacements Available (NRND). Verify current production status before design finalization. Direct substitutes within the same family must match the 14-bit resolution and 48-lead QFN package form factor.
