I am interested in replacing the LM1875s I currently use with class D chip amps.
The LM1875s are used in the power supplies for turntable motors, typical apps include a 3 phase supply for an EC motor (in a Garrard 301) and a quadrature supply for a synch motor.
It seems to me that with something like an AD 1992 or 1994 operating in bridged mono I could get at least as much power (currently 15W max per phase) but with a single supply and without big heatsinks. Any suggestions for other chips welcomed.
I would also like to know if anyone has any experience running these chips into highly inductive loads
