KAD5512HP-21Q48

Analog To Digital Converters (ADC) Overview

The KAD5512HP-21Q48 is a single-channel, 12-bit analog-to-digital converter (ADC) from the KAD5512 family. It operates at sampling rates up to 125 MSPS with an analog input bandwidth of 950 MHz and clock jitter of 60 fs. The device uses a pipeline architecture and accepts differential inputs. It functions on a single 1.8 V supply. Digital outputs are selectable as DDR LVDS-compatible or LVCMOS. Key performance metrics include an SNR of 68.2 dBFS at fIN = 105 MHz (-1dBFS) and SFDR of 81.1 dBc. Power consumption is 345 mW at 125 MSPS in SDR mode. It is housed in a 48-lead QFN package.
