LAG668 Tape Player Magnetic Head Amplifier Board Bass Headphone Amplificati DC

Description: LAG668 Tape Player Magnetic Head Amplifier Board Bass Headphone Amplificati DCLAG668 Tape Player Magnetic Head Amplifier Board With Bass Headphone Amplification Description: Notice: Only Magnetic Head Amplifier Board, Not include any other Accessories. The circuit adopts the new original LAG668, a single-chip audio player IC design with a subwoofer circuit, which is an upgraded product of the LAG665, with a motor speed stabilization circuit, a subwoofer circuit, and a headphone amplifier output. Add a mini movement and you can assemble a good tape player. The IC is designed with a subwoofer circuit, which can be realized by setting the pin headers on the board. The output of the board can be directly played by earphones and small speakers. When listening with headphones, the dynamic range is wide and works well even at low volume. Basic technical indicators: front stage closed-loop gain (Gvc) 42dB, distortion (THD) O. 05%, input impedance 22K. The power amplifier voltage gain is 38dB, and the left and right channel attenuation error is 0dB. Parameters: Working Voltage: DC 2.8V~3.3V (Battery power is recommended, Suitable for mini movement assembly) Working Voltage: DC 2.8V~5.0V (Suitable for benchtop large movement assembly, The motor of the large movement should not be connected to the motor interface on the board, it cannot be driven) Applicable Magnetic Head: 180ohm-350ohm dual-channel magnetic heads. Output Power: 30mW+30mW Board Size: 50mm x 25mm (L*W) Notice: 1, Since the LAG668 headphone amplifier output does not share the ground, if it needs to be connected to the power amplifier, the power supply cannot be shared with the power amplifier, and must be separated, otherwise the sound will be abnormal and cannot be used. 2, Assembled with a mini movement, the power supply cannot exceed 3.5v. If the voltage is too high, the motor speed stabilization circuit will be burned. If you need to use a 3.7v lithium battery for power supply, you can connect a rectifier diode in series with the positive pole of the power input to reduce the voltage (use IN4001-IN4007), (if the motor speed stabilization interface is not used, the power supply can be used between 2.8v-5v).
