SNR: 90dB
Efficiency:> 90%
Maximum closed-loop gain: 24DB
Note:
1: Do not reverse the positive and negative of power supply.voltage can not exceed 5.5V,
Otherwise, immediately burn IC
2: On-chip high-gain buffer, the board can not change any component parameters
and do not meet the parameters will result in IC damage.
3: The input line, please try to use shielded cable, interference can play a role in removing clutter current sound.
4: output cmos tube BTL drive, so the speaker can be connected together without the negative,
