Our shop specially developed the AD630 lock-in amplifier module for weak signal detection, which can be used for modulation, detection, amplification and other functions. With our chopper amplifier module, filter module, high-precision phase shifting module, DDS module, we can detect and extract weak signal, which is very convenient.

Parameters:

[Name]: AD630 Balanced Modulator

[Size]: 50mm * 50mm

[Supply Voltage Range]: ±5V

AD630 is a high precision balanced modulator with flexible commutation structure and excellent accuracy and temperature stability provided by thin film resistors adjusted by laser wafers. 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. On-chip resistance network provides precise closed-loop gain of S 1 and S 2 with an accuracy of 0.05% (AD630B). These resistors can also be used to precisely configure multiplexers: +1, +2, +3 or+4. Alternatively, external feedback can be used to allow designers to achieve high gain or complex switching feedback topologies

Chip characteristics:

(1) The signal can be recovered from 100 dB noise.

(2) Channel bandwidth: 2MHz

(3) Voltage swing rate: 45 Wus

(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: 100V (AD630BD)

(8) 350 kHz full power bandwidth
