DG212BDY-E3 application field and working principle

DG212BDY-E3 is an SPDT (Single Pole Double Throw) analog switch that can be used for multiplexer, demultiplexer and other interface applications. DG212BDY-E3 is ideal for analog signal routing, signal attenuation, level translation and power management.

Features

DG212BDY-E3 features:

• Low On-Resistance
• Wide Single Supply Operation
• Low Charge Injection
• Rail-to-Rail Signal Performance
• Minimal Power Consumption
• Industry Standard SOIC-8 and MSOP-8 Packages
• TTL/CMOS Control Compatible

Applications

DG212BDY-E3 is suitable for multiplexing/demultiplexing applications and interfaces, such as:

• Analog multiplexer applications
• Analog demultiplexer applications
• Level translation
• Power management
• Signal and power routing
• Signal attenuation

Working Principle

The DG212BDY-E3 has two control inputs and one signal output. The signal output is connected to one of the two inputs depending on the control input state. The device is typically used as a multiplexer or demultiplexer, depending on the configuration.When the two control inputs, S0 and S1, are both low (in the logic 0 state), the signal output is connected to the A input. When one of the control inputs is high and the other is low (one in logic 0 and the other in logic 1 state), the signal output is connected to the B input. Finally, when both control inputs are high (in the logic 1 state), the signal output is connected to the Z input. When the control inputs are in this state, the switch is in the “off” position and the signal can not pass through the switch.

Conclusion

The DG212BDY-E3 is an ideal single-pole double-throw analog switch for use in multiplexers and demultiplexers, level translation, power management, signal and power routing and signal attenuation applications. The device features low on-resistance and minimal power consumption, with rail-to-rail signal performance and a wide single-supply operation range. The device is also TTL/CMOS compatible and available in two industry-standard packages, SOIC-8 and MSOP-8.
