Reland Sun AD630 2-Channel Balanced Modulator/Demodulator Lock-in Amplifier Module for Weak Signal Detection

Description

• 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 (AD630BD) (8) 350 kHz Full Power Bandwidth

Description:
The AD630 lock-in amplifier module is specially developed for weak signal detection, which can be used for modulation detection, amplification and other functions. With chopper amplifier module, filter module, high-precision phase shift module, DDS module, etc., it can detect and detect weak signals. extract.

Parameter:
SizeSupply voltage range:5V
Crosstalk:-120dB
Channel bandwidth:2MHz

Note:
The module defaults to phase lock function, IN1 is the signal to be detected, IN2 is the synchronization signal, and OUT is output.
The onboard low-pass filter needs to be configured by the user before it can be used. It can be switched by a jumper cap.

AD630 is a high-precision balanced modulator with a flexible commutation structure and a thin film resistor adjusted by a laser wafer to provide excellent accuracy and temperature stability. Its signal processing applications include: balanced modulation and demodulation, synchronous detection, phase detection, quadrature detection, phase sensitive detection, lock-in amplification, and square wave multiplication. The on-chip application resistor network provides precision closed-loop gains of 1 and 2 with an accuracy of 0.05% (AD630B). These resistors can also be used to precisely configure the multiplexer gain: +1, +2, +3, or +4. Alternatively, external feedback can also be used, allowing designers to implement high gain or complex switch feedback topologies.
