Frequently Asked Questions
What output power and headphone impedance range does the TPA6120A2DWPR support?
The TPA6120A2DWPR delivers 1.5 W nominal output power per channel at maximum supply conditions, making it capable of driving headphones from 16 Ω to 600 Ω. Low-impedance 32 Ω consumer headphones receive more than adequate current, while high-impedance 300 Ω or 600 Ω studio reference models are driven with sufficient voltage swing for full-scale listening.
Can TPA6120A2DWPR operate from a single USB or battery supply in portable designs?
Yes, the TPA6120A2DWPR supports single-supply operation from 10 V to 30 V, which is achievable with a boost converter from a 5 V USB or a 3.7 V lithium battery. For portable DAC/amplifier designs, a charge pump generating ±5 V from a single cell meets the minimum dual-supply requirement, enabling full 22 kHz bandwidth audio playback.
How does TPA6120A2DWPR's audio bandwidth compare to general-purpose op-amps used as headphone drivers?
The TPA6120A2DWPR is specified to a nominal 22 kHz audio bandwidth, but its current-feedback topology provides a slew rate and gain-bandwidth product far exceeding general-purpose voltage-feedback op-amps at equivalent gain settings. This results in lower total harmonic distortion at high frequencies compared to op-amps with only 1 MHz gain-bandwidth product driving low-impedance loads.
What package does the TPA6120A2DWPR use and how many channels are integrated?
The TPA6120A2DWPR integrates 2 independent amplifier channels in a 20-pin Small Outline Package (SOIC) with a compact PCB footprint. The 20-pin SOIC body measures approximately 12.8 mm × 7.5 mm, providing enough pins for separate input, output, and feedback networks for both left and right audio channels in a single surface-mount device.
