KAD5512P-17Q48

Analog To Digital Converters (ADC) Overview

The KAD5512P-17Q48 is a single-channel, 12-bit analog-to-digital converter (ADC) from the Renesas Intersil KAD5512P family. It operates at a sampling rate of 125 MSPS with a pipeline architecture and differential input type. The device supports both LVDS and LVCMOS digital output formats and interfaces via parallel and SPI ports. It functions on a single 1.8V supply for both analog and digital domains. 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.
