The 80-pin, 12- × 12-mm TQFP EPAD-up package greatly reduces thermal-management constraints on the PCB layout. Many operational amplifiers (op amps) are used at low signal levels—think of ...

But once you’ve found a short, it’s up to you to figure out which part of the circuit it’s in – a tedious job on a large PCB with hundreds ... single AD8534 quad op amp chip.
