Working Principle

The AD844SQ/883B is a linear amplifier that employs optical isolation to isolate the input signal from the output. The device operates in a differential mode, where a single input signal is translated into a differential output. The output voltage is proportional to the input voltage and is determined by the gain setting. The gain control is set by adjusting a resistor between the output and the reference voltage input. The device can also operate in a single-ended mode, where the gain setting is set using a resistor between the input and output.The device also has over-current and over-voltage protection, which prevents excessive current from flowing through the circuit, or excessive voltage from being applied to the output. This protection feature helps to protect the device from damage due to accidental over-current or over-voltage conditions.

Conclusion

The AD844SQ/883B is a linear amplifier and optical isolator that is widely used in a variety of applications. This device is specifically designed for use in instrumentation, medical and industrial applications, where precise gain control and optical isolation are required.
