The firm has a significant market share lead in converter chips, which are used to translate analog signals to digital and vice versa. The company serves tens of thousands of customers; more than half of its chip sales are to industrial and automotive end markets. ADI's chips are also incorporated into wireless infrastructure equipment.

The wireless business contributes nearly 70% of AT&T's revenue. The company is the third-largest US wireless carrier, connecting 74 million postpaid and 17 million prepaid phone customers. Fixed-line enterprise services, which account for about 14% of revenue, include internet access, private networking, security, voice, and wholesale network capacity. Residential services, about 11% of revenue, primarily consist of in-home broadband internet access, serving 15 million customers. AT&T also has a sizable presence in Mexico, with 25 million wireless customers, but this business only accounts for 3% of revenue. The company recently sold its 70% equity stake in satellite television provider DirecTV to its partner, private equity firm TPG.
