Analog Devices
16 V Auto-Zero, Rail-to-Rail Output Operational Amplifiers
The AD8639AR is an uncategorised made by Analog Devices in a SOIC8 package with 8 pins. 16 V Auto-Zero, Rail-to-Rail Output Operational Amplifiers.
PCBKit's library has its KiCad symbol (Operational Amplifiers:Operational Amplifier x2 Type1 [alt], from CERN's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 2 open-source boards in 2 repositories on GitHub use it.
