TAS6511QPWPRQ1

Overview

The TAS6511QPWPRQ1 is a single-channel Class-D audio amplifier from Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 4.5V to 18V and delivers up to 50W into a 2-ohm load or 30W into a 4-ohm load. The device features a THD+N of 0.02% and supports a switching frequency of 2MHz. It is housed in a 28-HTSSOP package with an operating temperature range of -40°C to 125°C.

Feature Summary

• Single-channel mono output configuration optimized for high-power audio applications
• Automotive-grade qualification compliant with AEC-Q100 standards
• High efficiency Class-D topology supporting wide supply voltage ranges

Applications

• Automotive center channel speaker systems
• Vehicle trunk subwoofer amplification
• High-power single-driver audio setups in cars

Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive grade specifications. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Check for specific revision levels or process change notifications that may affect mechanical dimensions or electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-power solution is required for automotive environments. Ensure the thermal design accommodates the power dissipation at maximum output levels. Verify that the load impedance matches the expected power delivery ratings. Consider the 28-pin HTSSOP package constraints for PCB layout and heat sinking requirements compared to alternative packages like VQFN.

Part Context

This part belongs to the TAS6511-Q1 family of automotive audio amplifiers. It is distinct from other TI audio ICs by its specific focus on high-power monaural output. The Q1 suffix indicates automotive qualification. It differs from stereo variants by providing only one output channel, making it suitable for dedicated woofer or center channel roles rather than full-range stereo pairs.

Replacement Considerations

Check for TAS6511QRGERQ1 which offers similar functionality in a VQFN-24 package. Verify pin-to-pin compatibility and thermal performance differences between the HTSSOP and VQFN footprints before substitution.
