This Product Selection Guide contains information to help select products in the Analog Switches - Special Purpose category on DigiKey.com
Special Purpose Analog Switches route analog signals via a solid-state device. The differentiator in this family is that these Analog switches target a specific application, and as such have distinguishing features not typically found in general purpose Analog switches.
SelectionCharacteristics
Applications: Indicates the use of the part.
Multiplexer/Demultiplexer Circuit: Indicates channel configuration(s) of the switching mechanism(s) in a device.
Switch Circuit: Describes device function in terms of a number of poles and throws, as is common for mechanical switches.
Number of Channels: Defines the number of channels for the switch.
On-State Resistance (Max): Characterizes the maximum resistance of a controlled/switched current path through a device when that path is closed, connected, or “on.” Measured under manufacturer-defined test conditions.
Voltage - Supply, Single (V+): Describes permissible supply voltage span when a single supply voltage is used.
Voltage - Supply, Dual (V±): Describes permissible supply voltage span when dual supplies (positive and negative with respect to a common reference or “ground”) are used.
-3db Bandwidth: Characterizes a device’s high-frequency signal limitations, indicating the frequency at which signals passed through a device would be attenuated by 3dB.
Features: Special performance and safety characteristics built into the part.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier’s device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer-specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
