KAD5512P-12Q48

Analog To Digital Converters (ADC) Overview

The KAD5512P-12Q48 is a single-channel, 12-bit analog-to-digital converter (ADC) from the KAD5512P family. It features a sampling rate of 125 MSPS and utilizes a pipeline architecture with differential input. The device operates on a single 1.8 V supply for both analog and digital domains. Digital outputs are configurable as LVDS or LVCMOS, supporting parallel and SPI interfaces. Key performance metrics include a signal-to-noise ratio (SNR) of 67.1 dB, integral nonlinearity (INL) of 2.5 LSB, and differential nonlinearity (DNL) of 0.8 LSB. Power consumption is specified at 235 mW typical, with an operating temperature range of -40°C to +85°C in a QFN-48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify component status carefully as this model is designated as End-of-Life (EOL). Manufacturers indicate that production will cease, and no new orders should be placed for design-in purposes. Sourcing is limited to existing stock or secondary markets. Confirm RoHS compliance details directly with suppliers before procurement. Due to the EOL status, lead times may be unpredictable, and availability is not guaranteed. Validate part authenticity through authorized channels to avoid counterfeit risks associated with obsolete components.

Analog To Digital Converters (ADC) Selection Notes

Select this component only if legacy compatibility with the KAD5512P family is required. Consider the KAD5512HP variant for improved SNR performance if pin compatibility allows. Evaluate alternative modern ADCs if new designs do not mandate specific interface constraints. Ensure system requirements align with the 125 MSPS maximum sampling rate and 1.8 V supply voltage. Verify that the QFN-48 package footprint fits the target PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the KAD5512P series of high-speed, low-power ADCs developed by Renesas Electronics (formerly Intersil).
