Audio Amplifiers datasheet and documents for MAX9789AETJ+
Audio Amplifiers Overview
The MAX9789AETJ+ is a Windows Vista-compliant audio amplifier IC integrating a stereo Class AB speaker amplifier, a DirectDrive headphone amplifier, and a low-dropout linear regulator. It operates on a single 4.5V to 5.5V supply within a 32-pin thin QFN package measuring 5mm x 5mm x 0.8mm. The device delivers 2W of output power for speakers and 100mW for headphones. Key electrical specifications include a power supply rejection ratio of +90dB and a total harmonic distortion plus noise of 0.002%.
Audio Amplifiers Feature Summary
- Integrates a 2W stereo Class AB speaker amplifier with a 100mW DirectDrive headphone amplifier.
- Includes an internal 120mA LDO providing stable voltage support for external codecs.
- Eliminates the need for large output coupling capacitors in headphone circuits.
- Features built-in pop-and-click suppression to minimize transient switching noises.
Audio Amplifiers Applications
- Microsoft Windows Vista compliant laptop systems
- Portable multimedia players
- Tablet computers
Audio Amplifiers Procurement Notes
Verify component authenticity through authorized Analog Devices channels due to obsolete status. Confirm package integrity as the 32-pin thin QFN form factor requires careful handling during assembly. Ensure design compatibility with existing thermal management solutions given the integrated LDO and dual amplifier architecture.
Audio Amplifiers Selection Notes
Select this component for designs requiring high-fidelity audio performance with minimal external passive components. The integrated DirectDrive technology simplifies headphone driver interfaces by removing DC-blocking capacitors. Verify that the system power budget accommodates the 120mA LDO load alongside the amplifier requirements.
Audio Amplifiers Part Context
This part belongs to the Maxim Integrated audio amplifier family designed specifically for portable computing platforms. It combines multiple audio functions into a single compact solution, reducing board space and bill of materials complexity compared to discrete implementations.
Audio Amplifiers Replacement Considerations
The MAX9789AETJ+ is marked as obsolete. Designers should evaluate alternative audio amplifier solutions from current product lines that offer similar integration levels and pin compatibility.
