Overview
The TAS5611APHDR is a Class-D audio amplifier manufactured by Texas Instruments, housed in an HTQFP-64 package. It delivers 125 W stereo or 250 W mono output with a THD+N of 0.03%. Operating on analog inputs, it supports 2 Ohm and 4 Ohm loads within a 16 V to 34.1 V supply range. The device functions between 0°C and +70°C, drawing 20 mA quiescent current with an 80 kHz GBP.
Feature Summary
- PurePath HD architecture for high-fidelity analog input amplification
- Dual-channel configuration supporting stereo or bridged-mono modes
- Integrated thermal and short-circuit protection mechanisms
Applications
- High-power home theater systems
- Professional audio amplifiers
- Active loudspeaker designs
Procurement Notes
Verify the specific suffix APHDR against the official datasheet to confirm the tape-and-reel packaging format and temperature grade. Ensure compatibility with the required 64-pin HTQFP footprint during PCB layout. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.
Selection Notes
Select this component when high power density and low distortion are critical for analog-driven applications. The 125W/250W ratings suit demanding audio environments. Verify that the system design accommodates the 16V to 34.1V supply requirements and the specific thermal dissipation needs of the HTQFP-64 package.
Part Context
Part of the TAS5611A series, this device represents a high-performance power stage solution. It integrates advanced digital control features typical of the PurePath HD family while accepting standard analog inputs. The component is designed for robust operation in consumer and professional audio equipment requiring significant output power.
Replacement Considerations
Check for TAS5611PHDR if tray packaging is preferred, noting potential differences in operating temperature ranges. Evaluate TPA3245DDVR as a modern alternative, though specifications differ. Always consult official substitution guides for electrical compatibility.
