Audio Amplifiers datasheet and documents for LM4926TL/NOPB

LM4926TL/NOPB

Audio Amplifiers Overview

The LM4926TL/NOPB is a stereo headphone amplifier manufactured by Texas Instruments, housed in a DSBGA-14 package. It delivers 80mW into a 16Ω load with less than 1% THD+N from a 3V supply. Operating voltage ranges from 1.6V to 4.2V. The device features an internal fixed gain of 1.5V/V and ultra-low shutdown current of 0.01µA. PSRR at 217Hz is typically 70dB. It includes automatic standby mode and advanced pop-and-click suppression circuitry.

Audio Amplifiers Feature Summary

Ground-referenced outputs utilizing an internal charge pump to eliminate the need for output coupling capacitors.
Automatic standby mode reduces power consumption when no input signal is detected for approximately 12 seconds.
Independent micro-power shutdown capability for each channel via dedicated control pins.
Advanced circuitry eliminates audible transients during turn-on and turn-off transitions.

Audio Amplifiers Applications

Notebook PCs
Mobile Phones
PDAs
Portable Electronic Devices
MP3 Players

Audio Amplifiers Procurement Notes

Verify the NRND status before implementation, as this indicates the component is not recommended for new designs. Confirm that the DSBGA package type aligns with your PCB layout capabilities. Ensure all electrical parameters meet system requirements prior to finalizing procurement decisions.

Audio Amplifiers Selection Notes

Select this component for applications requiring minimal external components due to the elimination of large output capacitors. Consider the low operating voltage range suitable for battery-powered devices. Evaluate the thermal performance within the DSBGA package constraints if high ambient temperatures are expected.

Audio Amplifiers Part Context

This part belongs to the LM4926 series of ground-referenced audio amplifiers. It is designed specifically for mobile phone and other low-voltage applications where minimal power consumption is critical. The technology allows for high-quality output power with a minimal amount of external components.
