Overview

The AD7859ASZ is an analog To Digital Converter made by Analog Devices in a MQFP-44(10x10) package with 44 pins. -40℃~+85℃ 12 1LSB 200kHz 3V~5.5V 8 Parallel port MQFP-44(10x10) Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AD7859BS, from EasyEDA) and its footprint (generated:QFP-44_10x10mm_P0.8mm, from generated from its package), ready for a KiCad board. 4 are in stock at JLCPCB (part C651766).
