Mini Audio Amplifier using IC AN7115

Mini Audio Amplifier using IC AN7115
This is the mini audio amplifier circuit which built using power IC AN7115 as the main part. Tipically, with 9VDC supply and 4Ω loudspeaker, this amplifier will deliver about 2.1W. When the supply voltage (Vcc) is 9.0VDC , THD = 10% , RL = 8Ω, the output power of AN7114 can be up to 1.4W, the noise output is 3mV. (more…)
