Greetings,
I have some pre-stuffed TPA3116R2 boards from overseas that is set up as a single channel mono PBTL amp.
However, they have the mode setting as 26dB Slave, with the SYNC input grounded.
It seems to be working fine...just want to make sure it is ok.
It is set up as follows:
AVCC =PVCC = +12V
MODSEL = GND (BD mode)
SDZ = FAULTZ with 100k pullup to PVCC
PLIMIT = GVDD with 1uF to GND
GAIN/SLV = R1=75k, R2=47k (26dB Slave)
LINP=LINN = GND (PBTL)
AM0 thru AM2 = GND
SYNC = GND
Output Inductor and caps: 10uH with 1uF to GND, 0.22uF bootstraps, 3.3ohm and 10n snubbers.
Driving single 4 ohm speaker with ~12in leads.
Questions:
1. Is Slave mode correct for a stand alone PBTL amp?? Should I use Master and open the SYNC pin?
2. Should I be using 1SPW mode? (a little more distortion is tolerable, but I would like to minimize standby current).
