This is a high precision balanced modulator that combines a flexible commutation architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin-film resistors.
The AD630 is a high-precision balanced modulator combining a flexible commutating architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin-film resistors. It is intended for use in precision signal processing and instrumentation applications requiring wide dynamic range, such as balanced modulation, demodulation, synchronous detection, and lock-in amplification.
Key features include pin programmable closed loop gains of +1 and +2 with 0.05% accuracy, a 2 MHz channel bandwidth, and extremely low crosstalk of -120 dB @ 1 kHz. The device is available in various packages including Plastic DIP, Side Brazed DIP, and Leadless Chip Carrier.
