Headphone Amplifier Evaluation Board
Linear Integrated Systems headphone amplifier evaluation board is a complete, low-power stereo audio amplifier for high-fidelity line-level output and headphone applications. It consists of Linear Integrated Systems JFETs along with a number of other parts mounted on a circuit board.
Linear Integrated Systems headphone amplifier evaluation board includes the following features:
- Stereo, single ended input and single ended output
- 400 mW output power into 100Ω
- Wide frequency response (10Hz?200kHz; ?1dB)
- Voltage gain 5 (14dB)
- Low distortion (THD+N is less than 1% at 10Hz?20kHz at 5Vrms into 100Ω and less than 0.1% from 10 Hz to 20 kHz at 1Vrms into 100Ω load)
- Short circuit protection
- Pop reduction (slow start) circuit
- Defeatable cross feed circuit
- Volume control
- Overvoltage and reverse polarity power protection
- Audio input and output connections: left and right RCA phono jack inputs, ¼” stereo phone jack output
- External 9V–16V supply input
- External power supply connector: power jack, inside diameter 2.1mm, outside diameter 5.5mm
