We make vibration control equipment and would like to use the Class D TPA3255 Amplifier in Parallel Bridge Tied Load mode to drive a 300+ watt dynamic shaker and would like to be able to sense the output current being driven to the shaker which will be in the 0 to 12 Amp range. We are designing a new PC board for the power amp and then there will be discrete wires connected to the shaker. We are looking for the best way to monitor the current to the shaker, preferably through a PC mounted sensor or via the inter-connecting wires. Any thoughts, comments or suggestions on what TI sensors might best fit this application would be greatly appreciated.
Best regards,
