Taidacent Lockin Amplifier AD630 Module Minimum System Phase Sensitive Detection Weak Signal Conditioning Balanced Modulation

This AD630 lockin amplifier is an integrated OPA627 preamplifier and 4thorder ultra lowpass Butterworth filter forming a set of lockin amplification of the smallest system that can detect and extract weak signals but also available Modulation function to AD630 The AD630 is a highprecision balanced modulator with a flexible commutation structure and offers laser laser waferadjusted thin film resistors with excellent accuracy and temperature stability Its signal processing applications include balanced modulation and demodulation synchronous detection phase detection quadrature detection phase sensitive detection lock amplification and square wave multiplication In the lockin amplifier circuit when it is used as a synchronous demodulator it can recover weak signals in a 100 dB noise background The AD630s optimal operating frequency is at 1 kHz Chip features 1 The signal can be recovered from 100 dB noise 2 Channel bandwidth 2 MHz 3 Slew rate 45Vus 4 Crosstalk 120 dB 1 kHz 5 PinProgrammable ClosedLoop Gain 1 and 2 6 Closedloop gain accuracy and matching 005 7 Channel Offset Voltage 100 uV AD630BD 8 350 kHz full power bandwidth.
