PCB Board / ALPS16 / ALPS27 NE5532 ±15V Fully Direct-coupled Dual op amp Pre-stage Preamplifier board (Upgraded Version)

You have Three options:

● 1pcs PCB Board
● 1pcs ALPS16 Potentiometer Version Finished Board
● 1pcs ALPS27 Potentiometer Version Finished Board

Upgraded version:

● Increase the main capacitor.
● Increase the potentiometer.
● Use fast recovery diodes.
● The power supply voltage is increased from 12v to 15v.

Features:

● The Pre-stage adopts full direct coupling circuit design, no input, output, decoupling capacitors
● Especially suitable for LME49720NA/HA such ultra-low temperature drift operational amplifier, no matter how it is used, the zero drift is very small.
● It can give full play to the low frequency and high resolution characteristics of LME49720NA/HA.

Product Description:

● The board's operational amplifier adopts TI NE5532 and an operational amplifier seat, which is easy to upgrade.

● Integrated power, volume, and preamplifier in one

● Suitable for LM3886/TDA7293/LM4766/LM1875 as front stage

● LM317/337 is used for high-precision voltage stabilization, with voltage stabilization accuracy and ripple rejection ratio 78/79 higher by a grade

● Operational amplifier power supply ±15V

● 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)

● The ALPS 16 or 27 potentiometer can be used for volume control.

Parameters:

● Printing board size: 9.6mm×5.8mm, 2mm thick printing board, 70um thick copper foil
● Power supply Voltage: ±15v
● Magnification: 4.3 times
