Overview
The TAS5613ADKD is a high-performance analog input Class D amplifier from the PurePath HD series, housed in a 44-pin PSOP3 package. It delivers up to 150 W stereo into 4 Ω or 300 W mono PBTL into 2 Ω using a single 36 V supply. The device features integrated closed-loop feedback for ultra-low 0.03% THD at 1 W and >100 dB SNR. Operating conditions include a PVDD range of 18 V to 38 V and GVDD/VDD of 10.8 V to 13.2 V.
Feature Summary
- PurePath HD active enabled integrated feedback technology
- Multiple configuration support including BTL, PBTL, and SE modes
- Self-protection design with undervoltage, overtemperature, clipping, and short circuit protection
Applications
- Home Theater Systems
- AV Receivers
- DVD/ Blu-ray Disk Receivers
- Mini Combo Systems
- Active Speakers and Subwoofers
Procurement Notes
Verify the specific ordering suffix DKD corresponds to the 44-pin PSOP3 package variant. Confirm thermal interface material requirements between the exposed heatslug and heat sink to achieve rated power levels. Ensure system designs utilize recommended decoupling capacitors and output filters to maintain EMI compliance and audio performance specifications.
Selection Notes
Select this component when a thermally enhanced 44-pin surface mount package is required for high-power applications. It serves as a pin-compatible alternative to the TAS5630, TAS5615, and TAS5611 within the same family. Consider the DKD package's thermal resistance characteristics relative to the PHD option based on PCB layout constraints.
Part Context
This part belongs to the TAS5613A PurePath HD analog input power stage family. It utilizes Texas Instruments' advanced digital modulation architecture combined with analog inputs. The device integrates four independent half-bridges capable of flexible channel configurations, providing high efficiency and low distortion for demanding audio environments.
