KAD5514P-25Q72

Analog To Digital Converters (ADC) Overview

The KAD5514P-25Q72 is a single-channel, 14-bit analog-to-digital converter (ADC) from Renesas Electronics. It operates at a maximum sampling rate of 250MSPS with an analog input bandwidth of 950MHz. The device utilizes proprietary FemtoCharge technology on a standard CMOS process and requires a single 1.8V supply voltage. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.9dB and a Spurious-Free Dynamic Range (SFDR) of 84.9dB. It features programmable gain, offset, and skew control via an SPI interface. The component is housed in a 72-lead QFN package with an exposed paddle and supports industrial temperature ranges.

Analog To Digital Converters (ADC) Feature Summary

• Supports selectable digital output formats including DDR LVDS-compatible or LVCMOS for flexible system integration.
• Includes programmable built-in test patterns and selectable clock divider ratios of ÷1, ÷2, or ÷4.
• Features low-power operation with nap and sleep modes to optimize energy consumption during idle periods.
• Provides extensive configurability through a Serial Peripheral Interface (SPI) port for fine control of gain and offset.

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR) systems requiring high dynamic range and wide bandwidth.
• Test and measurement equipment needing precise digitization of high-frequency signals.
• Military and aerospace radar signal processing applications.
• Medical imaging systems utilizing ultrasound or MRI technologies.

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. Ensure compatibility with the required 1.8V power supply rails and check for any end-of-life notifications or recommended replacement parts within the KAD5514P family before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel ADC with 14-bit resolution and sampling rates up to 250MSPS is required. Consider the KAD5514P family if pin compatibility with other resolutions like 10-bit or 12-bit is needed for design flexibility. Evaluate the need for LVDS versus LVCMOS outputs based on board trace length and noise immunity requirements.

Analog To Digital Converters (ADC) Part Context

The KAD5514P-25Q72 belongs to the KAD5514P family of low-power, high-performance ADCs. This family includes variants with different sampling rates such as 125MSPS, 170MSPS, and 210MSPS. All members share similar architectural features and pinouts, facilitating easy upgrades or downgrades in designs without significant PCB layout changes.

Analog To Digital Converters (ADC) Replacement Considerations

KAD5514P-12, KAD5514P-17, and KAD5514P-21 are pin-compatible alternatives within the same family offering lower sampling rates. Verify that the reduced bandwidth and speed of these substitutes meet the specific application requirements before substitution.
