TITPA2005D1DRBQ1
Overview
The TPA2005D1DRBQ1 is an AEC-Q100 qualified, filter-free Class-D audio power amplifier designed for space-constrained automotive applications. It delivers up to 1.45W of mono output into an 8-ohm load from a 5.5V supply while maintaining high efficiency. The device features a fully differential architecture that provides excellent immunity to noise and RF interference.
Why Choose This Part
The filter-free Class-D architecture eliminates the need for bulky LC output filters, reducing both PCB area and BOM cost. Its AEC-Q100 qualification and wide -40C to +85C operating range ensure reliability in harsh automotive environments, while the 250-kHz switching frequency and high PSRR simplify power supply design.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the TPA2005D1EVM evaluation module to test audio performance and thermal characteristics. When designing the PCB, place the 1uF ceramic bypass capacitor as close as possible to the VDD pin to minimize noise. Ensure the exposed thermal pad of the 8-SON package is soldered to a grounded copper plane for optimal heat dissipation.
