This device contains two high-current amplifier circuits designed for linear servo loads, including voice coil motors. Manufacturer-documented applications also include motor drivers, audio power amplifiers, power oscillators, and linear voltage regulators.\u003cbr\u003e\u003cbr\u003eSeparate supply connections for the input and output stages support boost or bootstrapping arrangements to increase output swing. Current-sense connections support feedback for transconductance operation. The photographed component has a metal mounting tab with two mounting holes.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eTwo power operational amplifiers in one package.\u003cbr\u003eOperating supply range of ±3 to ±20 V DC.\u003cbr\u003ePeak output current up to ±3.5 A for 50 ms.\u003cbr\u003eUnity-gain stable with low crossover distortion.\u003cbr\u003eOutput current sensing and current limiting.\u003cbr\u003eInternal thermal shutdown and output protection diodes.\u003cbr\u003ePower-tab package for attachment to suitable heat sinking.\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eFor circuits specifically designed for the ULN3755W electrical connections, supply requirements, and thermal limits.\u003cbr\u003eThe ULN3755B uses a different 16-pin DIP package and is not a direct physical replacement.\u003cbr\u003eVerify the W-package pinout and mounting arrangement before installation.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A:\u003cbr\u003eQ: Is this a single or dual amplifier?\u003cbr\u003eA: It contains two power operational amplifiers.\u003cbr\u003e\u003cbr\u003eQ: Can it continuously deliver 3.5 A?\u003cbr\u003eA: No. ±3.5 A is the peak absolute maximum rating for 50 ms. Continuous-current absolute maximum ratings are ±2.0 A at ±15 V supplies and ±2.5 A at ±6 V supplies; actual operation also depends on heat dissipation and operating conditions.\u003cbr\u003e\u003cbr\u003eQ: Is the metal mounting tab electrically isolated?\u003cbr\u003eA: No. The manufacturer identifies the heat sink connection as the negative supply, or ground in a single-ended application.\u003cbr\u003e\u003cbr\u003eQ: Is additional heat sinking required?\u003cbr\u003eA: Heat sinking must be selected for the circuit’s power dissipation and temperature. The tab alone does not establish an allowable continuous output power.\u003cbr\u003e\u003cbr\u003eTroubleshooting:\u003cbr\u003eThe manufacturer requires an output R-C compensation network; component values depend on the load.\u003cbr\u003eKeep input and output grounds separate and provide high-frequency supply bypassing with ceramic or film capacitors.\u003cbr\u003eKeep input, output, and supply leads short.\u003cbr\u003eIf current sensing is unused, return the current-sense connections to the negative supply or applicable ground.\u003cbr\u003eIf boost operation is unused, connect the boost inputs to the positive supply.\u003cbr\u003eCheck the W-package connection diagram before applying power.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003ePlease review all photos and specifications before purchasing, and make sure this part is right for your application.
