AD630 Lock-In Amplifier Module, 2MHz Bandwidth, 45 V/μs

Summary

• Flexible: The AD630's application flexibility makes it ideally suited for applications requiring accurate fixed gain, switching gain, multiplexing, integrated switching capabilities, and high accuracy amplification.
• 100 dB Dynamic Range: The AD630's 100 dB dynamic range exceeds that of any hybrid or IC balanced modulator or demodulator and is comparable to that of expensive signal processing instruments.
• Operational Amplifier Design: The operational amplifier design of the AD630 is easy to implement for high gain or complex switching feedback functions. The application of resistors facilitates the implementation of the most common applications without the need for additional devices.
• Multiplexer: The AD630 can be used as a 2 channel multiplexer with gains of 1, 2, 3, or 4. 100 dB of channel isolation at 10 kHz is close to the limit that can be achieved with an empty IC package.
• No Calibration Required: In most cases, the AD630 module's laser tuning and amplification channel offsets do not require external zero calibration.
