TAS5751M output power cannot reach the designed maximum, and it is easy to saturate
One of our audio products uses 2 pcs TAS5751M
TAS5751M Powered by VDD = 24V
2X30W
One of the TAS5751M uses BTL mode to output 2X30W 8R
Problem phenomenon:
The power cannot reach the designed maximum power value,at present, it can only be saturated up to 15W.
2X20W
Another TAS5751M uses BTL mode to output 2X20W 8R
Both circuits are powered by VDD = 24V
Problem phenomenon:
The power cannot reach the designed maximum power value,at present, it can only be saturated up to 3W.
Please help to see if the schematic is normal? What causes the saturation? Thanks!
