Rangkaian 3 volt Mini amplifier
This is a mini 2W audio amplifier is suitable for small handheld radios and other portable audio gadgets. The amplifier circuit can be run from 3Volt. This Mercury is ideal for battery operated module. The potentiometer circuit can be used to control volume. Capacitor C1 and C2 are designed to filter supplyvoltage If the battery separator is used as operations offer source.For using batteries C1 and C2 are not required.
Profit TDA 7052 is set internally at 40 dB. . Compensate for the reduction of output power due to low voltage TDA7052 uses Bridge-Tied-Load principle(BTL), which can provide power about 1 to 2 W RMS (THD = 10%), 8 ohm load to the power supply 6 V.
