COMING SOON - there was a mistake on the Rev A PCB. We want to fix it before making it available. If you are interested in getting the Rev A anyway please contact us and we'll give you a discount to help get rid of the old stock. They will need a couple jumper wires to get it working right.
This is a power amplifier module based around the OPA549 by Texas Instruments.
The OPA549 is 0.050" off the back edge of the PCB to be mounted onto a heat sink if needed.
These amplifiers work great for audio and also work great with amplifying a DAC output to control devices or have a programmable voltage.
8A continuous current, 10A peak. +/-4 to +/- 30 V, or +8 to +60. Module setup with dual supplies in mind.
Module supplies local bypassing with ceramic caps and large electrolytic ones. Output protection diodes installed (bottom side). Adjustable current limit via one low-power resistor. Topology setup to either by inverting, non-inverting, or as a difference amplifier. Replace 0805 resistors to change the gain and topology.
