MAX4297 - Mono/Stereo 2W Switch-Mode (Class-D) Audio Power Amplifiers

Download the MAX4297 datasheet PDF. This datasheet also covers the MAX variant, as both devices belong to the same mono/stereo 2w switch-mode (class-d) audio power amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX4295/MAX4297 mono/stereo, switch-mode (Class-D) audio power amplifiers operate from a single +2.7V to +5.5V supply.

Key Features

  • include a 1A current limit, thermal protection, and under-voltage lockout. The MAX4295 (mono) and MAX4297 (stereo) reduce the number of required external components. Both devices have internal high-speed power-MOS transistors, allowing operation as bridge-tied load (BTL) amplifiers. 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 i.

19-1746; Rev 1; 2/01 Mono/Stereo 2W Switch-Mode (Class-D) Audio Power Amplifiers General Description The MAX4295/MAX4297 mono/stereo, switch-mode (Class-D) audio power amplifiers operate from a single +2.7V to +5.5V supply. They have >85% efficiency and are capable of delivering 2W continuous power to a 4Ω load, making them ideal for portable multimedia and general-purpose high-power audio applications. The MAX4295/MAX4297 feature a total harmonic distortion plus noise (THD+N) of 0.4% (fOSC = 125kHz), low quiescent current of 2.8mA (MAX4295) or 4.6mA (MAX4297), high efficiency, and clickless power-up and shutdown. The SHDN input disables the device and limits supply current to <1.5µA (MAX4295) or <2.3µA (MAX4297).
