Taidacent Balanced Modulator/Demodulator AD630 Chip Lock-in Amplifier Module for Weak Signal Detection Modulation Detection
The module locks the function by default, IN1 is the signal to be detected, IN2 is the synchronous signal, OUT outputs. The onboard low-pass filter requires the user to configure it to use, and switch through the jumper cap. (1) The signal can be recovered from 100 dB noise (2) Channel bandwidth 2 MHz (3) Slew rate 45V/us (4) Crosstalk -120 dB (1 kHz) (5) Pin programmable, closed-loop gain ±1 and ±2. (6) Closed-loop gain accuracy and matching 0.05% (7) Channel Offset Voltage 100 uV (8)
