MAX4295ESE+

The MAX4295ESE+ is a mono, 2W, switch-mode class D audio power amplifier in 16 pin NSOIC package. It has greater than 85% efficiency and is capable of delivering 2W continuous power to a 4ohm 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 SHDN input disables the device and limits supply current to less than 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.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 85°C
• 0.7W/channel output power at 3V
• Logic programmable PWM frequency selection 125KHz, 250KHz, 500KHz, 1MHz
