The NC7WB66K8X_G is an analog switch IC designed by ON Semiconductor. It is part of the CompactLogix™ Switch family and offers a high level of integration, low-voltage operation, and excellent switching performance. The device integrates two independent analog switches in a single package, allowing for more flexibility and improved power efficiency in application designs.

The SWITCH family of devices offers a wide range of control and multiplexing solutions with an integrated package. The NC7WB66K8X_G specifically offers two independent switches, controlled by a standard logic signal, with low on-resistance, adjustable hysteresis, low on-leakage, low supply current and excellent signal-to-noise ratio. This device is ideal for applications that require switching one signal form one source to another such as load cell measurements and multiplexing of analog signals.

It is a low on-resistance switch, with 10 ohm maximum. It provides high signal-to-noise ratio with low charge injection and low audible pop noise when ON and OFF switching. The maximum ON capacitance of the switch is typically 12.5 pF. It can be powered from a wide supply voltage range, from 0.9V up to 5.5V with a maximum supply current of 1µA. The NC7WB66K8X_G is an ESD-protected device, offering robustness when subjected to high Electrostatic Discharge.

The NC7WB66K8X_G facilitates multiple analog switches with a single package and its major features are:

• Low on-resistance RON
• Robust ESD protection on all terminals
• Low Leakage Current
• Low ON Capacitance
• Low supply current
• Wide Supply Range

Due to its numerous features, these NC7WB66K8X_G chips can be used in a variety of application fields, such as:

• Digital motor drives
• Audio mixers
• Data acquisition systems
• Video switches
• Automatic test equipment (ATE)
• System level multiplexing

The NC7WB66K8X_G provides two independent analog switches with a simple design, making it an ideal solution for multiplexing of analog signals. It works on the principle of a CMOS driver, using an external logic control signal to control the switch. The logic signal can be either a high voltage or low voltage level such as a 0V or +5V. This makes it easier to control the switching of the signals. The device\'s low power, low on-resistance, and low on-capacitance all make it an attractive option for multiplexing applications.

The NC7WB66K8X_G can also be used as a digital to analog converter, in which logic signals are converted to analogue voltages. This is done through a digital to analogue converter (DAC) which is connected to the voltage output of the switch. The DAC converts the logic signals to analogue output currents, which can then be used to drive loads such as potentiometers, servo motors, LED drivers, and VGA monitors.

In conclusion, the NC7WB66K8X_G is an excellent choice for multiplexing of analog signals, as it offers excellent performance and low power in a compact package. The wide supply voltage range and adjustable hysteresis make it a great switch for many applications. It is also ideal for use in audio mixers and ATE systems, as well as digital to analog conversion.
