Other Parts Discussed in Thread: TAS5825M, TAS5805M
I am using the TAS5751M in a battery application where the PVDD supply will vary from 12V to 24V. When testing the EVM under a moderate condition 1.5W into PBTL 4 Ohm loads (0.75W per output), the output changes with PVDD. For example if PVDD=24V and the gain is set to provide 1.5W output power when I drop the supply to 12V, or -6dB, the output also drops 6dB. I need the level to be stable as the battery discharges. We would like to avoid adding a boost converter but if this is the only option can you recommend one the is readily available?
