KAD5514P-17Q48

Analog To Digital Converters (ADC) Overview

The KAD5514P-17Q48 is a single-channel, 14-bit analog-to-digital converter (ADC) from the KAD5514P series manufactured by Renesas Electronics. It operates at a maximum sampling rate of 170 MSPS with a differential input structure and pipeline architecture. The device utilizes a single 1.8V supply for both analog and digital domains, consuming approximately 378 mW to 406 mW of power. Digital outputs are available in LVDS or LVCMOS formats. Key performance metrics include a signal-to-noise ratio (SNR) of 70.6 dB, integral nonlinearity (INL) of 3.5 LSB, and differential nonlinearity (DNL) of 1 LSB. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 48-lead QFN package.

Analog To Digital Converters (ADC) Feature Summary

• Supports programmable gain, offset, and skew control via a Serial Peripheral Interface (SPI) port for precise parameter configuration.
• Features FemtoCharge technology on a standard CMOS process to achieve low power consumption while maintaining high-speed conversion capabilities.
• Includes selectable clock divider options (÷1, ÷2, or ÷4) and clock phase selection to accommodate various system timing requirements.

Analog To Digital Converters (ADC) Applications

• Wireless communication base stations
• Software-defined radio systems
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

This component is designated as End-of-Life (EOL). The manufacturer has announced that production will cease, and the part is no longer recommended for new designs. Verification of final shipment dates and last-time buy availability is required before procurement planning. Supply chain stability cannot be guaranteed for future manufacturing cycles.

Analog To Digital Converters (ADC) Selection Notes

Designers should evaluate alternative components from the same family or newer generations due to the EOL status. Considerations must include pin compatibility, interface standards (LVDS/LVCMOS), and sampling rate requirements. Verify that replacement parts meet the specific SNR, INL, and power consumption specifications of the original design.

Analog To Digital Converters (ADC) Part Context

The KAD5514P-17Q48 belongs to the KAD5514P family of high-performance ADCs, which includes variants with different sampling rates such as 125 MSPS and 250 MSPS. This specific model represents the 170 MSPS tier within the 14-bit resolution segment. The Q48 suffix indicates the 48-lead QFN package option, distinguishing it from other package configurations like the 72-lead variant.

Analog To Digital Converters (ADC) Replacement Considerations

No officially confirmed substitute part numbers are publicly documented for this discontinued component. Engineers must identify third-party equivalents or next-generation Renesas products that match the electrical and mechanical specifications independently.
