Taidacent OPA541 OP AMP High Power Monolithic Operational Amplifier 5A Current High Voltage Audio Amplifier Sound Amplifier Board
Key features
- •Name: OPA541 High Voltage High Current Power Amplifier; Size: 96mm*64mm*41mm (length, width, height); Supply voltage range: ±10V~±40V
- •The OPA541 module is a power operational amplifier capable of operating with a power supply up to 40V and providing continuous output current up to 5A. The internal current limiting circuit can be controlled by the user using a single external resistor to protect the amplifier and load from fault conditions.
- •Suitable for motor-driven speaker drive, transformer drive and audio amplifier. It can also amplify triangle wave, sine wave and square wave signals.
- •The power consumption of the module is large, and the power supply requires a certain margin. It is recommended to use a power supply with a current driving capacity greater than twice the output current. The module can only be powered by dual power supplies. In order to avoid unnecessary interference, it is recommended to use a linear power supply, the power supply should not exceed plus or minus 40V.
- •The output signal is recommended to use the SMA to BNC cable to directly observe the effect of the oscilloscope. Poor contact or poor quality wires may cause signal attenuation or excessive noise.

Great product for general use and excellent support
Claran Martis✓ Verified Purchase•August 4, 2023
Bought this to get higher current at different frequencies and works very well within the ratings. The board works for up to 100kHz. The board came with a schematic that was very helpful. It allowed me to modify the circuit for my application and get higher bandwidth.
Great buy
Brian Stempien✓ Verified Purchase•July 21, 2023
This Op Amp works great for our purposes. If we need another one would buy this one again.
Well behaved!
Buzzard Bait✓ Verified Purchase•June 15, 2023
Comes with a schematic and contact info. The sch. routing is correct but not some of the values. This device is DC coupled throughout. Easy to mount. Nice heat-sink size for forced air cooling or lower power natural convection. Layout looks very good. The terminals are not that good as it's hard to get enough torque on the screws due to the head design but I know good ones are spendy so they will do.
In my case I'm using it as a buffer for my workbench so I removed R5 (a shunt), set the gain to unity and used SMA P1 as an input. Feeding it with +/- 15 Volt at 4 Amps from two supplies. I've used it to buffer my function generator and it's fine well past 100 kHz in sine. Seems happy with inductive loads. I tried speakers, motors, transformers and everything is well behaved. Buffering me bench supply shows the DC offset is nil and tracking is near perfect. Output noise is very low---less than 2 mV rms when sourced with my linear supply running 10 Volts.

Rolls off at about 100khz
Michael D✓ Verified Purchase•May 7, 2023
This amplifier comes with a print of the circuit diagram and works extremely well up to about 100khz, at which point a sine wave starts to shrink and eventually become distorted. Great general purpose amplifier, I'll see if I can modify it for higher frequency operation.
