QA460 Transducer Driver [RETIRED]
The QA460 has been replaced with the QA461.
The QA460 is a general-purpose amplifier designed to drive everything from speakers and other reactive loads you might encounter while developing your product.
Additional sense ports on the QA460 make it easy to measure speaker impedance. Simply route the sense resistor outputs of the QA460 to the right channel on the QA401, and you can make fast impedance measurements of speakers and other low impedance transducers at up to 1W or more. See this link here for more details.
The QA460 includes a 12V/1.5A brick. For US customers, this will be a Tri-Mag L6R18-120. For customers outside the US, this will be a Phihong PSAA18U-120L6. Both have UL/CB/CE safety ratings, Class B EMI, 90-264V AC inputs, and Level VI efficiency.
For customers outside of the US, you will need to provide your own cord to go from your local power standard to the IEC C14 input.
