The two companies are discussing an all-stock deal, the WSJ report said, referencing unnamed sources.
Maxim is also an analog and mixed-signal IC specialist suggesting some overlap with ADI but the former has sought to be a fab-lite and focus on application-specific integration in such sectors as industrial, automotive and health care.
Maxim has been up for sale before. In January 2016 Analog Devices and Texas Instruments both passed on the opportunity to buy Maxim on the grounds the price was too high. Also in 2016, ADI bought Linear Technology, a competitor to Maxim at the time, for $14.8 billion.
