AD630ARZ-RL

The AD630ARZ-RL is a high-precision balanced modulator/demodulator from Analog Devices Inc. (ADI). This versatile IC combines a flexible commutating architecture with the accuracy and temperature stability afforded by laser wafer trimmed thin film resistors. It offers a network of on-board application resistors that provide precision closed-loop gains of ±1 and ±2 with 0.05% accuracy (for the AD630B version). These resistors can also be used to configure multiplexer gains of 1, 2, 3, or 4 accurately.

Key features of the AD630ARZ-RL include:

1. High Precision and Stability: The AD630ARZ-RL leverages laser-trimmed resistors to ensure high precision and temperature stability, making it suitable for demanding signal processing applications.
2. Variable Gain Amplification: With on-board resistors providing precision closed-loop gains and the ability to configure multiplexer gains, the AD630ARZ-RL offers flexibility in gain settings.
3. Differential Inputs and Outputs: The IC features two independent differential input stages, allowing it to handle differential signals effectively.
4. Fast Comparator and Amplifier: The integrated comparator has a rapid response time, coupled with the high slew rate and fast settling of the linear amplifiers, minimizing switching distortion.
5. Wide Dynamic Range: The AD630ARZ-RL boasts a dynamic range of 100 dB, exceeding that of many hybrid or IC balanced modulators/demodulators and comparable to costly signal processing instruments.
6. Versatile Applications: This IC is ideal for precision signal processing and instrumentation applications requiring wide dynamic ranges, such as synchronous detection, phase detection, and balanced modulation and demodulation.
7. Additional Features: The AD630ARZ-RL also includes pin programmable frequency compensation, optional input bias current compensation resistors, common-mode and differential-offset voltage adjustment, and a channel status output that indicates which of the two differential inputs is active.

In summary, the AD630ARZ-RL is a high-performance, high-precision balanced modulator/demodulator from Analog Devices Inc. Its combination of accuracy, stability, flexibility in gain settings, and wide dynamic range makes it suitable for a variety of demanding signal processing and instrumentation applications.
