The WM9094ECS/R is a linear audio amplifier, designed primarily to drive headphones. It is a two-channel Class AB amplifier, with each channel delivering low-distortion, wide-bandwidth audio up to 2.7V peak-to-peak from a single 9V power source. It is capable of achieving a high-power output, and has low noise figures of 0.2μVrms.

It consists of a dual-channel amplifier module, which can be used in several different configurations. The amplifier module contains a differential-input amplifier, a buffer amplifier and a PNP output buffer. The module is capable of driving stereo headphones with single-ended or balanced inputs. The module can also be configured to drive up to 5 separate headphone channels with separate volume controls. The amplifier module can be configured as either an active or passive preamp, depending on the intended application.

The WM9094ECS/R amplifier offers two distinct advantages over other amplifiers in its class. The first is its excellent power dissipation. The module is capable of delivering up to 2.7V peak-to-peak of output power from a single 9V power source. This allows for a significant amount of additional headroom, resulting in higher sound quality and freeing up space on the circuit board.

The second advantage of the WM9094ECS/R is its linearity. The amplifier has very low distortion figures compared to other amplifiers in its class. The distortion figures range from 0.0015% at 1V RMS to 0.00025% at maximum output, with a signal to noise ratio of 110dB. This enables it to accurately reproduce the sound, providing natural and precise results.

The WM9094ECS/R is well-suited for a range of applications, such as home theatre systems and computer audio. It is capable of driving headphones with single-ended or balanced inputs, as well as stereo speakers for home theatre systems. It is also suitable for portable audio applications, as it consumes low power and has a very small footprint. Additionally, the amplifier module can be easily configured for multiple headphone channels with separate volume controls.

In short, the WM9094ECS/R is a linear audio amplifier with excellent audio performance, making it suitable for a range of audio applications. Its high power output and high-quality audio make it ideal for both high-fidelity audio systems and portable audio solutions. It is also capable of driving multiple headphone channels with separate volume controls, allowing for a greater range of sound options. Finally, its low noise and low distortion specifications enable it to accurately reproduce sound, making it an excellent choice for audio enthusiasts.
