The SN4910 is an audio power amplifier primarily designed for headphone applications in portable device applications. It is capable of delivering 35mW of continuous average power per channel into a 32Ω load with less than 1% distortion (THD+N) from a 3.3V power supply.

The SN4910 utilizes a new circuit topology that eliminates output coupling capacitors and half-supply bypass capacitors. It is ideally suited for low-power portable applications where minimal space and power consumption are primary requirements.

The SN4910 is also unity-gain stable and can be configured by external gain-setting resistors. Other features include click/pop suppression, low-power shutdown mode, short ground protection and thermal shutdown protection.
