KAD5514P-21Q72

Analog To Digital Converters (ADC) Overview

The KAD5514P-21Q72 is a single-channel, 14-bit analog-to-digital converter (ADC) from the KAD5514P family. It operates at a maximum sampling rate of 210 MSPS with an analog input bandwidth of 950 MHz. The device utilizes a pipeline architecture and FemtoCharge technology on a standard CMOS process. It requires a single 1.8 V supply voltage for both analog and digital sections. Key performance metrics include a Signal-to-Noise Ratio (SNR) of approximately 70.6 dB and an Spurious-Free Dynamic Range (SFDR) of 84.9 dB. The component is housed in a 72-lead QFN package and supports industrial temperature ranges.

Analog To Digital Converters (ADC) Feature Summary

• Features programmable gain, offset, and skew control via a Serial Peripheral Interface (SPI) port for precise signal conditioning.
• Supports selectable clock dividers (÷1, ÷2, or 〉4) and clock phase selection to accommodate various system timing requirements.
• Provides flexible digital output formats including DDR LVDS-compatible or LVCMOS outputs with selectable data formats such as two's complement, gray code, or binary.
• Includes low-power operational modes such as nap and sleep states to reduce energy consumption during idle periods.

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR) systems requiring high-speed digitization.
• Test and measurement equipment needing high linearity and wide dynamic range.
• Medical imaging systems utilizing ultrasonic or MRI technologies.
• Military radar and electronic warfare signal processing applications.

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 moisture sensitivity level (MSL) ratings prior to PCB assembly planning. Check for any end-of-life notifications or recommended replacement notices, as older ADC families may have limited long-term availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 14-bit resolution is required at sampling rates up to 210 MSPS. Ensure the system can support the 1.8 V power supply requirement and the thermal dissipation capabilities of the 72-lead QFN package. Verify that the interface logic levels match the available LVDS or LVCMOS options provided by the device.

Analog To Digital Converters (ADC) Part Context

The KAD5514P-21Q72 belongs to the KAD5514P family of low-power, high-performance 14-bit ADCs. This family includes variants with different sampling rates, such as the KAD5514P-12 (125 MSPS), KAD5514P-17 (170 MSPS), and KAD5514P-25 (250 MSPS). All members share pin compatibility and similar architectural features, allowing for design flexibility across different speed requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Public sources indicate that the KAD5514P series is not recommended for new designs. No direct alternative part numbers are officially confirmed as replacements. Designers should evaluate newer Renesas ADC families or third-party equivalents if current production is discontinued.
