Here is Current drive amplifier board for sale. I am working with current drive amplifiers maybe 15 years now. I don’t use boards with analog input myself, but decided to make one as sometimes I meet people interested in such board. Actually it is more mixed mode amplifier. Has 3 modes. Voltage mode and two mixed modes. Mixed mode where at low frequencies around resonance output impedance of amplifier is low, and above that is high. It is nothing extraordinary board. Made to be not very expensive. Uses LM3886 in composite configuration.
Some other features:
Clip protection/prevention
Overcurrent protection
Overtemperature protection
Silent turn on, turn of feature
Designed for SMPS supply
Onboard analog prefilter
Balanced input
And yes all COG caps in signal path and other obvious design things for good performance.
More things mentioned in my page and user manual is there https://www.baffless.com/analog-amp
Selling for 250Eur assembled and tested board. Without shipping from EU. You need power supply and heatsink. Good to tryout current drive. Quite a lot of posts about current drive, but no boards for sale as far as I know. In case current drive doesn’t fit your system, you can use it as voltage amp.
Before asking questions here please read the manual first.
