Product Details

The MAX4335–MAX4338 op amps deliver 40mW per channel into 32Ω from ultra-small SC70/SOT23 packages making them ideal for mono/stereo headphone drivers in portable applications. These amplifiers have a 5MHz gain-bandwidth product and are guaranteed to deliver 50mA of output current while operating from a single supply of 2.7V to 5.5V.

The MAX4336 and the MAX4338 have a shutdown/mute mode that reduces the supply current to 0.04µA per amplifier and places the outputs in a high-impedance state.

The MAX4335–MAX4338 have 90dB power-supply rejection ratio (PSRR), eliminating the need for costly preregulation in most audio applications. Both the input voltage range and the output voltage swing include both supply rails, maximizing dynamic range.

The MAX4335/MAX4336 single amplifiers are available in ultra-small 6-pin SC70 packages. The MAX4337/MAX4338 dual amplifiers are available in an 8-pin SOT23 and a 10-pin µMAX® package, respectively. All devices are specified from -40°C to +85°C.
