Overview

The AD6640ASTZ is an analog To Digital Converter made by Analog Devices in a LQFP-44(10x10) package with 44 pins. -40℃~+85℃ 1 1.25LSB 12 4.75V~5.25V 65MHz Parallel port LQFP-44(10x10) Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AD6640AST, from EasyEDA) and its footprint (Package_QFP:LQFP-44_10x10mm_P0.8mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C650445).
