Product Details
Purchasing and Inquiry
The TDA8947J contains a unique protection circuit that is only related to multiple temperature measurements inside the chip. This provides maximum output power for all power supply voltage and load conditions without unnecessary audio holes. Almost any combination of supply voltage and load impedance can be made as long as the thermal boundary conditions (number of channels used, external heatsink, and ambient temperature) permit.
The TDA8947J contains four identical audio power amplifiers. The TDA8947J can be used as four single (SE) channels with a fixed gain of 26dB, a bridged load (BTL) dual channel with a fixed gain of 32 dB, or a SE dual channel (gain of 26dB) and a BTL channel used as a 2.1 system (gain of 32 dB)
TDA8947J Feature:
SE:1 W to 25W, BTL:4 W to 50W operating range (2.1system)
flexible peak clipping
standby and silent mode
no on / concern
low standby current
high power supply voltage ripple removal rate
for grounding, power supply and cross-load output short-circuit protection
thermal protection
pins are compatible with TDA8944AJ and TDA8946AJ pins
TDA8947J Application:
TV
PC loudspeaker
