The MAX4295 mono, switch-mode (Class D) audio power amplifier operates from a single +2.7V to +5.5V supply. The MAX4295 has > 85% efficiency and is capable of delivering 2W continuous power to a 4Ω load, making it ideal for portable multimedia and general-purpose high-power audio applications.
The MAX4295 features a total harmonic distortion plus noise (THD+N) of 0.4% (fOSC = 125kHz), low quiescent current of 2.8mA, high efficiency, and clickless power-up and shutdown. The active-low SHDN input disables the device and limits supply current to < 1.5µA. Other features include a 1A current limit, thermal protection, and undervoltage lockout.
The MAX4295 reduces the number of required external components. Internal high-speed power-MOS transistors allow operation as a bridge-tied load (BTL) amplifier. The BTL configuration eliminates the need for isolation capacitors on the output. The frequency-selectable pulse-width modulator (PWM) allows the user to optimize the size and cost of the output filter.
The MAX4295 is offered in a space-saving 16-pin QSOP or narrow SO package.
