The HJ002 full-wave precision phase-sensitive demodulator is a monolithic full-wave phase-sensitive demodulation integrated circuit made using bipolar technology. It consists of two independent differential amplifiers, a precision comparator, and an analog switch. It can convert amplitude-modulated signals into full-wave rectified voltages and identify the phase of the input signal. The magnitude and polarity of the output DC voltage depend on the product of the amplitude of the input AC signal and the cosine of the phase difference between the input signal and the reference signal, independent of the amplitude of the reference signal. It features low zero-offset error voltage (typical value is 1-2mV), wide bandwidth (greater than 100kHz), low temperature drift (typical value is 10μV/°C), low power consumption, few external components, and high integration. It can be used in systems such as carrier suppression modulators, synchronous detectors, phase detectors, phase-sensitive demodulators, and lock-in amplifiers. It is mainly applied in automatic control systems and inertial navigation systems for detecting position states, as well as in situations requiring phase-sensitive demodulation of amplitude-modulated signals. This device has characteristics such as high precision, low drift, and high linearity, which help improve signal processing accuracy and carrier signal frequency. Its micro-packaging helps reduce electronic system size and enhance reliability.
