Description
TPA3110 Mono Digital Audio Amplifier Module is a 30 Watt mono high power, class D, digital audio amplifier module, which is based on TPA3110 chip set. It has an adjustable volume and supports mono audio using a 4/6/8 ohm (8 ohm is the best) speakers, which can be supplied with a voltage range from 8V DC to 26 volts DC. The module has a frequency response range of 20Hz-15KHz.
Because of using advanced EMI suppression technology, designers can use low cost ferrite bead filters for reaching EMC requirements. The SpeakerGuard™ speaker protection circuitry is designed with an adjustable power limiter and a DC detection circuit. The user by the adjustable power limiter can adjust a "virtual" voltage line, lower than the chip supply, which result in limiting the speaker current work. The DC detection circuit evaluates the PWM signal properties, means that measures and checks the frequency and amplitude of the PWM signal and if detecting any shifting or deviation because of damaging the input capacitors or shorting on the inputs, it cuts off the output. The module can drive a speaker at least 4 Ω, at 10% THD+N From a 16-V Supply. While it amplify the sounds, because of its high efficiency (90%), no need to use an external heat sink. The outputs have shorts to GND protection, shorts to VCC protection, and shorts output-to-output protection, completely. These short-circuit protection and thermal protection are associated with an
