KAD5512HP-17Q48

Analog To Digital Converters (ADC) Overview

The KAD5512HP-17Q48 is a single-channel, 12-bit analog-to-digital converter (ADC) from the KAD5512HP family. It operates at a maximum sampling rate of 170 MSPS with an analog input bandwidth of 950 MHz. The device utilizes Intersil’s FemtoCharge technology on a standard CMOS process and functions on a single 1.8V supply. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 68.8 dBFS and a Spurious-Free Dynamic Range (SFDR) of 81.1 dBc at an input frequency of 105 MHz (-1dBFS). Power consumption is specified at 390 mW in DDR mode and 309 mW in SDR mode at 125 MSPS. It features programmable gain, offset, and skew control, selectable clock dividers, and supports LVDS or LVCMOS output formats.
