TPA6101A2ZQYR

Audio Amplifiers Overview

The TPA6101A2ZQYR is a stereo headphone audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 1.6 V to 3.6 V and delivers 50 mW of output power per channel into a 16-ohm load. The device utilizes a Class-AB topology with a fixed gain configuration. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.4% and a quiescent current of 750 uA. It supports single-ended inputs and features a Microstar Junior 15-BGA package measuring 2.5x2.5 mm.

Audio Amplifiers Feature Summary

• Ultra-low voltage operation suitable for portable battery-powered devices
• Fixed-gain stereo architecture simplifies circuit design
• Compact Microstar Junior packaging for space-constrained applications

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix ZQYR corresponds to the Microstar Junior 15-BGA package variant rather than standard SOIC or other packages. Confirm that the fixed-gain specification aligns with system requirements, as this model lacks adjustable gain controls. Ensure compatibility with single-supply voltages between 1.6 V and 3.6 V during integration planning.

Audio Amplifiers Selection Notes

Select this component when a compact footprint is critical due to its small BGA package. It is appropriate for designs requiring low power consumption given its 750 uA operating current. Consider the fixed gain limitation if variable volume control is needed externally. Verify thermal management needs for the small form factor in enclosed spaces.

Audio Amplifiers Part Context

This part belongs to the TPA6101A2 family of ultra-low-voltage stereo headphone amplifiers. It shares core performance characteristics with variants like the TPA6101A2D but differs in physical packaging. The family is designed for mobile audio applications where size and power efficiency are primary constraints.

Audio Amplifiers Replacement Considerations

The TPA6101A2D serves as a pin-compatible alternative using an SOIC-8 package. Designers must account for the significant difference in footprint and thermal dissipation characteristics when substituting between the BGA and SOIC versions.
