The LM4903MM/NOPB amplifier is a low-power audio amplifier used in applications requiring low noise and power consumption. Its low saturation voltage and low-noise operational amplifiers provide exceptional audio performance.

The LM4903MM/NOPB is a single-supply audio amplifier suitable for mobile products and PC audio applications. It is a two-stage amplifier separated by an output stage. The first stage is based on a low-noise, wide-bandwidth operational amplifier. The second stage accepts the output of the first stage and sandwiches the signal between two NPN Darlingtons. This provides a low-saturation voltage output and enhances the flexibility of the amplifier.

The LM4903MM/NOPB amplifier offers a low-voltage, single-ended rail-to-rail voltage range. This allows for a maximum output of 8V peak-to-peak and a maximum input swing of 4V peak-to-peak. The amplifier also has a high-gain and very low distortion. This makes it perfect for audio applications that require low distortion and strong low-frequency response.

The output power of the LM4903MM/NOPB is controlled in two ways. First, the amplifier’s bias current is controlled by a voltage divider. This can be adjusted to provide the desired output power. Secondly, the amplifier’s output stage is designed with a switch that controls the power output. This allows for the output power to be set at the desired level.

The LM4903MM/NOPB amplifier is designed with a wide selection of gain settings. The amplifier can be easily configured for gains from 20 to 1000. This makes it suitable for a wide range of applications.

The LM4903MM/NOPB provides Stereo and Mono integration. Its stereo implementation is based on a differential-integrated amplifier (DIA) and its mono implementation is based on a single-ended amplifier. The stereo implementation supports two-channel audio and the mono implementation supports one-channel audio.

The LM4903MM/NOPB amplifier also includes a power-saving feature. This helps to reduce the power consumption of the amplifier. The power-saving feature is enabled by turning the amplifier off and on.

The LM4903MM/NOPB is a versatile, low-power audio amplifier. Its superior audio performance and low-power consumption make it well-suited for a variety of audio applications. Its low-voltage single-ended rail-to-rail voltage range and wide gain selection make it an excellent choice for a wide range of applications. Its stereo and mono integration, power-saving features and low distortion makes it a great choice for mobile products and PC audio applications.
