Model AD630 is an unusual new low-cost, single-chip, precision analog IC that can be used for the above functions with little or no additional circuitry. As a lock-in amplifier, it can recover a 0.1 Hz sine wave, transmitted as a modulation on a 400-Hz carrier, from a band-limited, clipped white-noise signal approximately 100,000 times larger—a dynamic range greater than 100dB.
