Product details
Frequently asked questions
What is the difference between TPA2012D2YZHT and TPA2012D2Y?
The TPA2012D2YZHT uses the NanoFree™ DSBGA package (2.24x2.16 mm), while the TPA2012D2Y uses a different package variant. Functionally both are the same Class D stereo amplifier core; the choice is footprint and board-level assembly compatibility.
Can TPA2012D2YZHT be used with 4 ohm speakers?
Yes, the TPA2012D2YZHT is rated to deliver 2.1W per channel into a 4Ω load, making it suitable for standard 4Ω portable speakers.
Can TPA2012D2YZHT drive 8 ohm speakers?
Yes, it can drive 8Ω speakers, though output power will be lower than the 2.1W into 4Ω rating. The amplifier is stable into 8Ω loads.
What is the efficiency of TPA2012D2YZHT?
As a Class D amplifier, the TPA2012D2YZHT typically achieves efficiency above 80% at moderate output levels, which minimizes heat dissipation in portable designs. The exact efficiency depends on supply voltage, load impedance, and output power.
