Overview

The AD1556ASZ is an analog To Digital Converter made by Analog Devices in a MQFP-44(10x10) package with 44 pins. -55℃~+85℃ 1 2.85V~5.25V 24 250Hz SPI、I2C MQFP-44(10x10) Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AD1556ASZ, from EasyEDA) and its footprint (generated:QFP-44_10x10mm_P0.8mm, from generated from its package), ready for a KiCad board. JLCPCB lists it (part C649027).
