1W series audio power amplifier of the LM4860 with a closed mode

General description

lm4860 is a bridge audio power amplifier, which can transmit the continuous average power of 1W to the 8Ω load of 8Ω of less than 1%(THD+N) on the audio spectrum of 1W from the audio spectrum. 5V power. Boomer audio power amplifier is specially packed on the surface with the least external components. Since the LM4860 does not require output coupling capacitors, self -raising capacitors or cushioning networks are suitable for low -power portable portable systems. The LM4860 is characterized by external control, low power consumption shutdown mode, and internal heat shutdown protection mechanism. It also includes two headphones control inputs and one headset induction output for external monitoring. The units of LM4860, which is stable in unit gain, can set the external compensation element of the external compensation element from an outer configuration differential gain to 1 to 10.
