KAD5514P-12Q72

Analog To Digital Converters (ADC) Overview

The KAD5514P-12Q72 is a single-channel, 14-bit analog-to-digital converter (ADC) from the KAD5514P family. It operates at a maximum sampling rate of 125 MSPS with an analog input bandwidth of 950 MHz. The device utilizes proprietary FemtoCharge technology on a standard CMOS process and requires a single 1.8 V supply. Key electrical parameters include a Signal-to-Noise Ratio (SNR) of 70.9 dBFS, Spurious-Free Dynamic Range (SFDR) of 84.9 dB, Integral Non-Linearity (INL) of 5 LSB, and Differential Non-Linearity (DNL) of 0.3 LSB. Power consumption is specified at 345 mW. It features LVDS or LVCMOS outputs and is housed in a 72-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'Q72' against official Renesas documentation to confirm the exact package variant and tape-and-reel specifications. Confirm RoHS compliance status and lead-free finish details directly with the manufacturer or authorized distributors. Check for any end-of-life notifications or recommended replacement notices prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 14-bit resolution is required at sampling rates up to 125 MSPS. Ensure the system design supports a single 1.8 V power supply and accommodates the thermal requirements associated with 345 mW power dissipation. Verify that the available SPI interface meets the configuration needs for gain and offset adjustments.

Analog To Digital Converters (ADC) Part Context

The KAD5514P-12Q72 belongs to the KAD5514P family of low-power, high-performance ADCs. This family includes variants with different resolutions and speeds, such as the KAD5514P-17, KAD5514P-21, and KAD5514P-25. These devices share pin compatibility within their respective bit-depth groups, facilitating design scalability across 10, 12, and 14-bit architectures with sample rates ranging from 125 MSPS to 500 MSPS.

Analog To Digital Converters (ADC) Replacement Considerations

Official documentation lists the KAD5514P-12 as No Recommended Replacements Available (NRND). Designers should evaluate alternative high-speed ADCs from other manufacturers if new designs are required, as no direct substitute part numbers are confirmed by Renesas for this specific model.
