PCB Board / ALPS16 / ALPS27 NE5532 ±15V Fully Direct-coupled Dual op amp Pre-stage Preamplifier board (Upgraded Version)
You have Three options:
¡Ü 1pcs PCB Board
¡Ü 1pcs ALPS16 Potentiometer Version Finished Board
¡Ü 1pcs ALPS27 Potentiometer Version Finished Board
Upgraded version:
¡Ü Increase the main capacitor.
¡Ü Increase the potentiometer.
¡Ü Use fast recovery diodes.
¡Ü The power supply voltage is increased from 12v to 15v.
Features:
¡Ü The Pre-stage adopts full direct coupling circuit design, no input, output, decoupling capacitors
¡Ü Especially suitable for LME49720NA/HA such ultra-low temperature drift operational amplifier, no matter how it is used, the zero drift is very small.
¡Ü It can give full play to the low frequency and high resolution characteristics of LME49720NA/HA.
Product Description:
¡Ü The board`s operational amplifier adopts TI NE5532 and an operational amplifier seat, which is easy to upgrade.
¡Ü Integrated power, volume, and preamplifier in one
¡Ü Suitable for LM3886/TDA7293/LM4766/LM1875 as front stage
¡Ü LM317/337 is used for high-precision voltage stabilization, with voltage stabilization accuracy and ripple rejection ratio 78/79 higher by a grade
¡Ü Operational amplifier power supply ±15V
¡Ü The finished board has no noise and the work is very stable (the low noise of the front stage is a major feature, and it is the benchmark for the front stage of our shop)
¡Ü The ALPS 16 or 27 potentiometer can be used for volume control.
Parameters:
¡Ü Printing board size: 9.6mm×5.8mm, 2mm thick printing board, 70um thick copper foil
¡Ü Power supply Voltage: ±15v
¡Ü Magnification: 4.3 times
