LM4910 - Output Capacitor-less Stereo 35mW Headphone Amplifier

Datasheet Summary

Description

The LM4910 is an audio power amplifier primarily designed for headphone 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.

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 at f = 217Hz 65dB (typ) n Power Output at VDD = 3.3V, RL = 32Ω, and THD ≤ 1% 35mW (typ) n Shutdown Current 0.1µA (typ) Features n Eliminates headphone amplifier output coupling capacitors (patent pen.

LM4910 Output Capacitor-less Stereo 35mW Headphone Amplifier February 2003 LM4910 Output Capacitor-less Stereo 35mW Headphone Amplifier General Description The LM4910 is an audio power amplifier primarily designed for headphone 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 pending). The LM4910 contains advanced pop & click circuitry which eliminates noises caused by transients that would otherwise occur during turn-on and turn-off.
