The main parameters of the tda7850 power amplifier are as follows:
Output type: 4 channels (4 channels),
Maximum output power x number of channels at different loads: 85W x 4@2ohms,
Voltage - Power supply: 8V ~ 18V,
Features: Silence, short circuit and thermal protection, standby.
Installation type: Through hole,
Operating temperature: -55°C ~ 150°C (TJ).
The function of the power amplifier is to amplify the weak signal from the sound source or the pre-amplifier and push the speaker to sound aloud.
A good sound system amplifier plays an important role.
IC chip output power is 4×50W, MOSFET output power level, low output noise ST-BY function
