Interface – Analog Switches, Multiplexers, Demultiplexers is a vast sector containing a large variety of components. Here we will be discussing the ADG722ACPZ-REEL7, a component from this family.

The ADG722ACPZ-REEL7 is a 2:1 analog multiplexer/demultiplexer with a selectable analog input utilization during multiplexing and a selectable low-power digital logic level is able to achieve higher reliability. This component is suitable for digital still cameras, cellular phones and portable data storage applications, thanks to its small size and low power consumption.

The ADG722ACPZ-REEL7 utilizes an on-chip high-impedance analog switch and an high-impedance logic-controlled switch active at low logic voltage. The low-power logic level is selectable with an external resistor and enables arbitrarily low logic levels for interfacing with single logic and dual logic systems. This component requires a low-voltage operation range from 0.75 V to 1.8 V with a maximum of 1.1 µA of supply current at Vdd = 1.8 V and 3 µA at Vdd = 1.6 V.

The ADG722ACPZ-REEL7 features selectable analog input utilization during multiplexing, which considerably reduces the amount of integration needed for the circuit. This means that fewer external components are needed to achieve the desired functionality. Additionally, this component has the capability of being used as a 2:1 multiplexer/demultiplexer. The multiplexer function is useful to select between two analog signals, while the demultiplexer function is useful to simultaneously process two analog signals.

Moreover, ADG722ACPZ-REEL7 includes a slew rate of 6 V/µs minimum and a switching time of 1.8 us maximum. This means that the time needed for the analog signals to be switched is very short and the dimensions of the circuit are very small.

The working principle of the ADG722ACPZ-REEL7 is dependent on the selectable analog input utilization during multiplexing. This requires a low-voltage operation range from 0.75 V to 1.8 V to be able to perform multiplexing and demultiplexing. When voltage is applied to the input of the multiplexer and then to the select pin of the switch, the switch will open and the analog value of the selected input will be passed through to the output.

Also, it is possible to use this component as a 2:1 demultiplexer which uses the same technique as a multiplexer in order to perform the demultiplexing function. In this case, the voltage is applied to the input of the demultiplexer and then to the select pins of the switches. When the voltage to the select pins exceeds the threshold voltage, the switch will open and the analog values of the selected input will be passed through to the outputs.

In addition, ADG722ACPZ-REEL7 includes a selectable low-power digital logic level that enables arbitrarily low logic levels for interfacing with single logic and dual logic systems. This function is essential to enable efficient interfacing with integrated circuitry. Also, the low power logic level can be adjusted using external resistors, which allows the user to control the logic levels for different applications.

The ADG722ACPZ-REEL7 is a versatile multiplexer/demultiplexer that offers a wide range of features. This component is ideal for applications requiring small size and low power consumption, such as digital still cameras, cellular phones and portable data storage applications. Also, this component can be used as a 2:1 multiplexer/demultiplexer and includes a selectable low-power digital logic level, making it suitable for interfacing with integrated circuitry. The low-voltage operation range, low power operation and quick switching time of this component make it an ideal choice for many applications.
