A week after a half-dozen Am Law 100 and Magic Circle firms divvied up work on SoftBank Group Corp.’s $32 billion buy of British semiconductor company ARM Holdings plc, three more large firms have landed roles on the latest big deal involving consolidation in the chipmaking sector.

Norwood, Massachusetts-based Analog Devices Inc. announced late Tuesday that it has agreed to acquire Linear Technology Corp. for $14.8 billion in cash-and-stock. The deal values the Milpitas, California-based target at $60 per share and will create a combined entity worth about $30 billion.
