I keep reading that the 4 drivers are TC4452's but the on this one there are 2 TC4422a's and 2 MIC4420ZT's. Can i replace all of them with TC4452's? It appears that the TC4422a's are for the low side and the MIC4420ZT's are for the high side. Does that sound correct?
The 4452s should be the right drivers. All should work (same pin configuration and non-inverting) but the 4452 appears to be the most rugged.
