Overview
The TPA005D14 is a monolithic stereo audio power amplifier integrating a Class-D section and a Class-AB headphone amplifier. It delivers 2 W continuous average power into a 4 Ω load at 0.4% THD+N from a 5 V supply. The device operates with low quiescent current, featuring a shutdown mode drawing 0.2 mA. It utilizes a thermally enhanced 48-pin PowerPAD TSSOP (DCA) package.
Feature Summary
- Integrates high-efficiency Class-D amplification for speaker outputs alongside a dedicated Class-AB headphone amplifier.
- Includes logic-controlled mode selection to activate either the main amplifier or the headphone stage while placing the inactive section in sleep mode.
- Provides comprehensive protection circuitry including thermal, over-current, and under-voltage lockout with status feedback terminals.
Applications
- Battery-powered portable audio systems requiring efficient power delivery
- Stereo speaker output stages in consumer electronics
- Integrated headphone amplifier solutions for mobile devices
Procurement Notes
Verify the specific ordering suffix when purchasing. The standard DCA package is available in left-ended tape and reel. To obtain the taped and reeled version, add the 'R' suffix to the part number (e.g., TPA005D14DCAR). Confirm the package type matches your board design requirements.
Selection Notes
Select this component for designs requiring both speaker drive and headphone output within a single IC. Ensure the application supports differential inputs and provides adequate power supply decoupling. Verify that the PCB layout accommodates the 48-pin PowerPAD TSSOP package for optimal thermal performance.
Part Context
This device belongs to Texas Instruments' line of extremely efficient Class-D stereo audio power amplifiers. It is designed to replicate analog input signals through high-frequency switching of power DMOS transistors, eliminating the need for external coupling capacitors on the BTL outputs.
Replacement Considerations
Texas Instruments suggests choosing the TPA2000D2 as an upgrade path for this product line.
FAQ
How does the device manage power consumption between the two amplifier sections?
Only one amplifier is active at any given time. When the Class-D amplifier is muted, the Class-AB headphone amplifier can be activated via the MODE pin, placing the other section in a power-saving sleep mode.
What fault conditions are monitored by the device?
The device monitors for thermal faults, over-current faults, and charge pump under-voltage lock-out (VCP-UV) faults. These conditions are reported via open-drain FAULT0 and FAULT1 terminals.
