Overview
The Texas Instruments TAS5612LADDVR is a high-performance PurePath™ HD digital input Class-D power stage. It utilizes a PWM digital input architecture with integrated on-chip feedback to achieve ultra-low distortion and high power efficiency. The device supports bridge-tied load (BTL) stereo mode delivering 2x125W into 4Ω loads, or parallel bridge-tied load (PBTL) mono mode providing up to 250W into 2Ω loads. Key electrical parameters include a THD+N of 0.03% at 1W/4Ω, a power supply rejection ratio exceeding 65dB, and an A-weighted signal-to-noise ratio of 105dB. It operates within a supply voltage range of 12V to 38V.
Feature Summary
- Integrates PurePath™ HD closed-loop feedback technology for precise output control independent of power supply fluctuations.
- Features low on-resistance MOSFETs and advanced gate drive schemes to minimize static and low-output signal losses.
- Includes pre-clipping output signals designed to optimize Class-G power supply control for enhanced system efficiency.
Applications
- High-power home theater systems
- Audio/video receivers
- Active subwoofers
- Professional audio equipment
Procurement Notes
Verify the specific suffix 'ADDVR' against official datasheets to confirm the tape and reel packaging format. Ensure compatibility with the required thermal management solutions for the HTSSOP-44 package. Confirm that the design supports the necessary digital PWM input interface rather than analog inputs.
Selection Notes
Select this component when a digital PWM input interface is available from the upstream processor. Compare performance metrics such as output power and efficiency against other TAS561x series variants. Evaluate the thermal requirements of the HTSSOP-44 package relative to the target enclosure constraints.
Part Context
This part belongs to the TAS5612LA series of PurePath™ HD digital power stages. It serves as a high-efficiency amplification solution for demanding audio applications requiring significant power output in a compact form factor.
Replacement Considerations
The TAS5614LADDVR offers higher power output capabilities within the same family. Designers should verify pinout compatibility and thermal performance differences before substituting models.
