Datasheet Details

Part number:

LM4910

Manufacturer:

National Semiconductor

File Size:

828.98 KB

Description:

Output Capacitor-less Stereo 35mW Headphone Amplifier

Features

* a low-power consumption shutdown mode, activated by driving the shutdown pin with logic low. Additionally, the LM4910 features an internal thermal shutdown protection mechanism. The LM4910 is also unity-gain stable and can be configured by external gain-setting resistors. Key Specifications n PSRR

Applications

* in portable device applications. It is capable of delivering 35mW of continuous average power to a 32Ω load with less than 1% distortion (THD+N) from a 3.3VDC power supply. The LM4910 utilizes a new circuit topology that eliminates output coupling capacitors and half-supply bypass capacitors (patent
