NF LI5640/5630 Phase-Locked Loop Amplifier Circuit Design

Model：LI5640/5630      Country of Origin：Japan      Category：Digital Phase-Locked Loop Amplifier

Overview：A lock-in amplifier is a measurement instrument for detecting repetitive signals (AC) buried in noise. It can also be regarded as a highly sensitive AC voltmeter with noise rejection capability. During measurement, except in some special cases, a reference signal is required. Generally, the signal source used for measurement is connected directly to the reference signal input. It is widely used in physical and chemical research fields such as spectroscopic analysis.
