This\nlaser-trimmed monolithic integrated circuit provides excellent low-level\nsignal accuracy and high output voltage and current. OPA549 adopts single\npower supply or dual power supply for design flexibility. OPA549 has internal\noverheating protection function conditions and current overload. In addition,\n0PA549 provides accurate, user-selected current limit. Unlike other uses of\n\"power\" resistors and output current paths, OPA549 indirectly detects the\nload. It is suitable for motor drive speaker drive, transformer drive and\naudio amplifier. It can also amplify triangle wave, sine wave, and square wave\nsignals. Parameter Module model 0PA549 Module type Low frequency power\namplifier Input signal form Single-ended Input voltage range 2Vpp (MAX),\ngenerally within the power supply Module input impedance 10KΩ Module supply\nvoltage ±4V—±30V Module power supply current ±8A, large output current\nrequires large power supply current Module output impedance Low resistance\nOutput voltage range 54Vpp (MAX), under positive or negative 30V power supply\nOutput current 8A (MAX), the module has set 6A current limit Output Power 100W\n(MAX) Module gain 33 times, the default gain is 33 times, the first stage is\n11 times, the second stage is 3 times, G1=R1\/R2+1, G2=R11\/R10+1 Input offset\nvoltage 1mV (MAX) Input offset drift 2uV\/℃(MAX) Input bias current 125nA (MAX)\nInput voltage noise 35nV Hz (1KHz) Module weight: 50g Module protection: No,\nno reverse connection protection, unlimited current protection Module\nspecification: 868152mm, length width height-PCB size Module heating:\nwith heat sink, forced air cooling is required for high current Module heating\nfactor: input and output voltage is too large or the module is damaged Module\nworking temperature: -40°C—+75°C, industrial grade Module features: positive\nand negative power LED indication Application: small signal amplifier, audio\nsignal amplifier, motor drive, servo amplifier, etc. Module interface type:\nSMA signal signal input and output, 5. 08 blue power card socket Module\ninterface diagram Precautions for module use (1) The power consumption of the\nmodule is large, and the power supply needs to have a certain margin. It is\nrecommended to use a power supply with a current drive capacity greater than 2\ntimes the required output current. The module can only be powered by dual\npower supplies. (2) In order to avoid unnecessary interference, it is\nrecommended to use linear power supply, and the power supply cannot exceed\nplus or minus 35V. (3) It is recommended to use the SMA to BNC cable for the\noutput signal to observe the effect directly with the oscilloscope. Poor\ncontact or poor quality cable may cause signal attenuation or excessive noise.\n(4) SMA port is not available for power output, blue terminal block must be\nused. The SMA port is for observing the signal and cannot be overpowered. (5)\nDue to the high power consumption and heat generation, pay attention to\nventilation and heat dissipation when working for a long time, and increase\nthe fan to strengthen heat dissipation when necessary. (6) Since the module\nhas a fixed magnification and no external protection circuit, it is\nrecommended to confirm the output power and amplitude before loading to avoid\ndamage to the module. Module test diagram Q: Is the magnification fixed? How\nto adjust it? A: The default magnification of the module is 33 times. If you\nneed to adjust the magnification, you can only change the resistance on the\nboard. The resistance package is 0805. The calculation formula has been given\nin the parameter details. Q: Can the module directly drive the coil? A: The\nmodule can drive the coil, but the internal resistance of the coil is required\nto be greater than 4Ω. If it is less than 4Ω, a power resistor must be\nconnected in series, otherwise the module may be damaged. Q: Can the module\namplify square waves or pulses? What is the bandwidth of the module? A: The\nmodule can amplify low-frequency square waves or pulses. Because it is an\naudio amplifier, the total bandwidth is not high. Signals within 100K can be\namplified. The module is compatible with DC input. Q: Can the module amplify\n1:1? That is, only amplify current? A: The module can support 1:1\namplification. You need to modify the resistance configuration magnification\nby yourself. It is not recommended to directly configure to the op amp\nfollower mode, which is easy to self-excite. It is recommended to change to\nresistance attenuation first, and then operational amplification. The total\ngain is 1. OK. Q: Why is the input sine wave output as a square wave? What is\nthe output current? What is the output power? A: Generally speaking, if the\ninput signal is too large, the operational amplifier will be amplified with\ncut-off distortion, which is a square wave, or the power supply voltage is not\nenough. It can be solved by reducing the input signal and increasing the\nsupply voltage. The output current of the module is determined by the output\nvoltage and load, 1=Uout\/R, the same is true, the output power P=U), which is\nalso determined by the output voltage and load resistance, heat dissipation\nsilicone grease and air cooling can be added for high power input. Q: Can I\nuse the second stage directly without the previous stage? A: You can only use\nthe second level, but you need to remove the first level chip, and then input\nthe signal from OUT1. Otherwise, the first-level chip will affect the signal\ninput.\u003c\/p\u003e \n\n\n \u003cul class=\"a\"\u003e\n \u003cli\u003eName: OPA549 Audio Power Amplifier Size: 86mm*81mm*52mm Supply voltage range: 10V~30V\u003c\/li\u003e\n \u003cli\u003eHigh-voltage, high-current audio power amplifiers can continuously output 8A with a maximum peak value of 10A, ideal for driving various loads such as motor drives, speaker drivers, transformer drivers, and audio amplifiers.\u003c\/li\u003e\n \u003cli\u003eOPA549's design flexibility supports single-supply or dual-source operation.
