Overview
The TPA0223DGQ is a mono Class-AB audio power amplifier manufactured by Texas Instruments, designed for headphone drive applications. It delivers 2 W of output power into a 4-ohm load and 90 mW into two 32-ohm loads. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V. Key electrical characteristics include a maximum quiescent current of 10 mA and a shutdown current of less than 1 µA. It features integrated pop-and-click suppression and input multiplexing capabilities.
Feature Summary
- Integrated pop-and-click suppression circuitry minimizes audible transients during power-up and power-down sequences.
- Input multiplexer allows selection between analog inputs or direct connection to a codec for simplified system design.
- Shutdown mode significantly reduces power consumption, making the device suitable for battery-operated portable electronics.
Applications
- Portable media players
- Mobile phones
- Personal digital assistants
Procurement Notes
Verify the specific suffix 'DGQ' corresponds to the 10-pin HVSSOP package when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management requirements are met for the selected operating environment.
Selection Notes
Select this component for designs requiring a single-supply mono amplifier with high efficiency and low distortion. It is appropriate for applications needing integrated headphone driving capabilities without external components. Compare against the TPA0213 and TPA0233 for alternative pinouts or feature sets if necessary.
Part Context
This part belongs to the TPA02xx series of audio amplifiers from Texas Instruments. These devices are optimized for portable consumer electronics, offering a balance of performance and power efficiency in compact packages.
Replacement Considerations
The TPA0223DGQG4 is a verified lead-free replacement variant within the same family. Verify package compatibility and electrical specifications before substitution.
