AD630 lock-in amplifier module phase-sensitive detection/weak signal conditioning/balance modulation -79401
product detail
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.
