Highlights:

This AD630 phase-locked amplifier is an integrated preamplifier OPA627 and 4-order ultra-low-pass Butterworth filter, forming a minimum system of phase-locked amplification, which can detect and extract weak signals, but also can be used for AD630 modulation function.

 

 

Parameters：

 

 

Function:

The module has two modes of operation, one is a phase-locked amplifier, the other is a balanced modulator.

Balanced modulator can leave a message or change the circuit itself after receiving the goods. The method is as follows:

1、Remove R4 (0-ohm resistance) and shorten or weld R3 to 0-ohm resistance

2、As shown in the figure, the mode selection is connected to the left and selected as the modulation mode.

3、Short-connect R14
