Frequently Asked Questions
What output power and supply voltage does the HPA01081RTJR support?
The HPA01081RTJR delivers 2.1 W per channel at a 5 V supply voltage, making it well suited for battery-powered portable audio equipment where space and power consumption are tightly constrained.
How does the 24 dB gain and 95 dB SNR of the HPA01081RTJR affect audio quality in a speaker design?
With a fixed 24 dB gain and a signal-to-noise ratio of 95 dB, the HPA01081RTJR provides clean amplification across the full 20 kHz audio bandwidth, reducing audible noise floor in loudspeaker designs for tablets and portable media players.
What package does HPA01081RTJR use and how does it compare to larger DIP alternatives for space-constrained layouts?
The HPA01081RTJR uses a 20-pin QFN package with an exposed thermal pad, occupying significantly less board area than traditional DIP packages while improving heat dissipation by conducting up to 1 W of waste heat directly through the pad to the PCB ground plane.
Is HPA01081RTJR a drop-in replacement for TPA2012D2RTJR in an existing 5 V stereo amplifier design?
Yes, HPA01081RTJR is functionally equivalent to TPA2012D2RTJR, sharing the same 20-pin QFN footprint, 2.1 W per channel output, 24 dB gain, and 5 V operating range, so it can serve as a direct PCB-level substitute without schematic changes.
