Use the Power Amplifier as a power supply for DC and AC circuit investigations or to drive devices such as speakers, lamps, and small DC motors.

ORDER CODE: PAMP Category

The Power Amplifier takes small input signal – from a LabQuest 2, original LabQuest, or computer – and amplifies it to produce voltages from -10 to 10 V and currents up to 1 A.

  • Can provide a steady, linearly-controlled DC output for driving loads like DC motors or DC circuits, and precise AC waveforms for driving things like RLC circuits and speakers.
  • Utilizes internal feedback for accurate AC waveforms (sine, square, triangle, and sawtooth) and DC levels.
  • Current-limited to protect against overload and shorting.
  • Current monitor function allows you to log real-time load current with any Vernier interface.
  • Class A-B Push-Pull Amplifier provides low distortion with good efficiency.
  • Supports input signals from the LabQuest 2 or original LabQuest’s Power Amplifier app, our free PC software Power Amplifier Function Generator (Windows or Mac), or Logger Pro 3.8 or newer (LabPro only).
  • Also supports an input signal from LabVIEW via the SensorDAQ interface.

Specifications

Technical Details of Power Amplifier Operation

  • Input connection: 3.5 mm audio cable (from LabQuest or computer) or BTA cable (from LabPro CH4)
  • Input Frequency range: DC to 15 kHz.
  • Overall gain: 10X (LabQuest/computer), 2X (LabPro)
  • Input impedance: 10 kΩ. (LabQuest/computer), 50 kΩ (LabPro)
  • Maximum input ±12 V without damage.
  • Pulse Width Modulation input used for producing DC offset or pure DC output

Current Sensor

  • Connect to Vernier interface to monitor load current
  • There is a 0.1 Ω resistor between the black terminal and ground. Current measurements are based on the voltage drop across this resistor.

Important Note: The Power Amplifier creates no signal on its own. It depends on a signal source, such as the LabQuest 2 or original LabQuest’s Power Amplifier App, our free Power Amplifier Frequency Generator software for PC/Mac, or Logger Pro 3.8 or newer (LabPro only)

A LabQuest Mini or LabQuest Stream does not provide a signal source. Use the Power Amplifier Function Generator software as the signal source.
