ADG2128BCPZ-REEL Application Field and Working Principle

The ADG2128BCPZ-REEL is an integrated IC employeed as analog switches in special purpose applications. It operates as 8 independent SPDT switches and provides constant break-before-make switching action. It has two independent channels, with 4 switches per channel, and each switch is coupled with an independent electronic switch control. Switches can be operated between 0V and VCC, with VCC voltage limited to 15V maximum.

Features

• Constant break-before-make switching action for both digital and analog control
• Voltage range from 0V to 15V
• High resistance to electrostatic discharge
• Low input bias current
• Low power consumption
• Simplified for UHF design
• Minimized susceptibility to EMI noise

Applications

The ADG2128BCPZ-REEL is used as analog switches in a wide variety of applications, such as audio and video switching, audio mixers, cell phone circuits, LED drivers, and so on. It can be employed to switch power, audio, and video signals, as well as analog and digital signals. It can be used in single, multiplexing, and multiplexing power applications.

Working Principle

The ADG2128BCPZ-REEL works using an integrated single-pole double-throw (SPDT) switch, which is composed of two separate transistors for each channel. Each switch is controlled by an independent electronic switch control signal. The switch can open or close, depending on the signal input to the switch control signal.

The switch output is the signal of interest, which can be either digital or analog. If a signal is digital, it is actively monitored continuously and when a logic one signal is inputted to the switch control, the switch closes and routes the signal as intended. If a signal is analog, it is also actively monitored continuously and once the signal exceeds the switch’s threshold voltage, the switch closes and routes the signal as needed.

The ADG2128BCPZ-REEL is a reliable solution for analog switching because it is highly resistant to electrostatic discharges and has low input bias current, low power consumption, and is minimized in susceptibility to EMI noise. By employing these features, this analog switch makes it easy to build efficient and fault-proof switching systems.

Conclusion

In conclusion, the ADG2128BCPZ-REEL is a versatile IC that can be employed as analog switches in a variety of applications. It works using an integrated SPDT switch, which can either be opened or closed depending on the input signal. It has numerous features, including high resistance to electrostatic discharge, low input bias current, low power consumption, and reduced susceptibility to EMI noise, making it an effective and reliable solution for analog switching.
