TPA0253DGQ

Overview

The TPA0253DGQ is a mono Class-AB audio power amplifier with an integrated headphone driver. It delivers 1 W to an 8-Ω speaker and provides 85 mW for headphones. The device operates on a single analog supply voltage ranging from 2.7 V to 5.5 V. Typical quiescent current per channel is 3.2 mA. It utilizes hardware control interfaces and features advanced power management technology. The component is housed in a 10-pin HVSSOP package with a PowerPad, suitable for surface-mount applications.

Feature Summary

• Integrated headphone amplifier capability alongside speaker drive functionality
• Advanced power management technology for enhanced efficiency
• Compact design optimized for space-constrained portable devices

Applications

• Portable media players requiring combined speaker and headphone outputs
• Mobile phones and smartphones with limited internal volume
• Personal digital assistants (PDAs) and handheld communication devices

Procurement Notes

Verify the specific suffix DGQ confirms the 10-pin HVSSOP package variant. Ensure the order specifies the standard tape-and-reel or tube quantity if applicable, though specific packaging metrics are excluded here. Confirm the operating temperature range of -40°C to 85°C matches your environmental requirements. Cross-reference the manufacturer's latest datasheet for any pinout revisions or RoHS compliance updates prior to finalizing procurement.

Selection Notes

Select this component when a single-chip solution is needed for both loudspeaker and headphone driving in mono configurations. It is appropriate for systems requiring low quiescent current to extend battery life. Consider the 10-pin HVSSOP package constraints for PCB layout. Verify that the analog input signal levels are compatible with the device's input impedance and gain structure before integration into the audio chain.

Part Context

This part belongs to Texas Instruments' TPA025x series of low-power audio amplifiers. The series focuses on integrating multiple audio output stages into a single compact package. The TPA0253DGQ specifically addresses the need for simultaneous speaker and headphone operation in mobile electronics, distinguishing itself from single-output amplifier variants within the same family.

Replacement Considerations

Check for direct pin-compatible substitutes within the TPA025x family. Verify that alternative parts support the same 1-W speaker and 85-mW headphone output specifications. Ensure the replacement maintains compatibility with the 10-HVSSOP package and the required 2.7-V to 5.5-V supply range.
