Overview
The TAS5614LADDVR is a PurePath™ HD digital-input Class-D power stage from Texas Instruments, housed in a 44-pin HTSSOP (DDV) package with an exposed thermal pad. It delivers 2x150W output in bridge-tied load stereo mode at 4Ω with 10% THD+N, and up to 300W in parallel bridge-tied mono mode at 2Ω. The device operates on a PWM digital input architecture with integrated feedback, achieving 0.03% THD at 1W/4Ω and >65dB power supply rejection ratio. It supports a supply voltage range of 12V to 38V and functions within a temperature range of 0°C to +125°C.
Feature Summary
- Integrates PurePath™ HD closed-loop feedback technology to minimize distortion and enhance power supply rejection.
- Features low on-resistance MOSFETs exceeding 90% power stage efficiency to reduce system heat generation.
- Includes pre-clipping output signals designed for controlling Class-G power supplies to improve overall system energy efficiency.
Applications
- Home theater systems
- AV receivers
- Soundbars
- Active subwoofers
Procurement Notes
Verify the specific ordering suffix 'DDVR' against the manufacturer's current datasheet to confirm the tape and reel packaging configuration. Ensure that the design accounts for the required humidity sensitivity level and soldering profile associated with this surface-mount package type during assembly.
Selection Notes
Select this component when designing high-power audio systems requiring digital PWM inputs rather than analog signals. The integrated feedback loop simplifies layout requirements by reducing sensitivity to power supply noise, making it suitable for applications demanding high fidelity without complex external compensation networks.
Part Context
This device belongs to the TAS5614LA series of high-performance digital power stages. It serves as a dedicated power amplification stage intended to be paired with external PWM modulators to construct complete high-fidelity digital amplifier solutions for consumer and professional audio markets.
Replacement Considerations
The TAS5614ADKDR is a documented alternative within the same family, though it features different operating temperature limits and packaging specifications compared to the LADDVR variant.
