TAS2770RJQR

Overview

The TAS2770RJQR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It features digital input and delivers 20 W of output power into a 4-ohm load. The device operates with a logic supply voltage range of 1.65 V to 1.95 V and an analog supply range of 4.5 V to 18 V. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.01% and a fixed gain of 21 dB. It is housed in a 26-pin VQFN-HR package measuring 4x3.5 mm and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates smart amplifier technology for optimized audio performance
• Includes built-in short-circuit and thermal protection mechanisms
• Supports digital PWM input interface for direct connection to processors
• Features shutdown mode for power management

Applications

• Smart speakers
• Soundbars
• Portable audio devices

Procurement Notes

Verify the specific suffix RJQR against the manufacturer's current datasheet to confirm the VQFN-HR-26 packaging and tape-and-reel configuration. Ensure compatibility with the required 1.65 V to 1.95 V logic supply and 4.5 V to 18 V analog supply rails during system design validation.

Selection Notes

Select this component for applications requiring high-efficiency mono audio amplification with digital control interfaces. The VQFN-HR package suits space-constrained designs, while the wide analog supply range allows flexibility in battery-powered or mains-powered speaker systems.

Part Context

This part belongs to the TAS2770 series of smart audio amplifiers from Texas Instruments. The series is designed for modern audio applications requiring high fidelity and integrated protection features within a compact footprint.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same family. Verify that any substitute maintains the 26-VQFN-HR package dimensions and digital input requirements.
