Interface - Analog Switches - Special Purposes

The HV20822FG-G is a special purpose analog switches manufactured by Fairchild Semiconductor. It is used to improve signal switching performance while maintaining a low on resistance. The digital control logic contains two digital control inputs and output which are highly compatible with TTL and CMOS logic. It has a high voltage standing gain of 300V, making it suitable for applications that require a high level protection.

The HV20822FG-G is designed for the following applications:

• Stereo systems
• Multi-track tape machines
• Audio-frequency signal switching
• Amplifiers
• Signal flow switching

The HV20822FG-G operates in two modes: single-operation mode and dual-mode operation. In single-operation mode, the switch is driven by the digital control input, and the output is generated by applying the input digital control signal to the switch to control the on/off state of the switch. In dual-mode operation, the internal logic of the switch is used to generate multiple outputs, which can be used for switching the output from the input signals.

The HV20822FG-G uses the nonlinear characteristic of the switching element to reduce switching power consumption. In dual-mode operation, two outputs are available to change the state of the switch. The digital outputs are open-collector type, making it more reliable and stable. In single-operation mode, the output can be controlled by the digital control voltage to ensure a stable output.

The HV20822FG-G is a highly reliable and well-designed analog switch suitable for various applications. It can be used in stereo systems, multi-track tape machines, audio frequency signal switching, amplifiers, and signal flow switching. Its high voltage standing gain, low power consumption, and superior reliability make it especially suitable for audio applications where performance and noise-free switching is necessary.
