DG211CSE+ is a family of Quad SPST (Single Pole Single Throw) switches in a 16-lead plastic SOIC package. The device is suitable for a variety of applications in the Analog, Digital, and Video arena. The DG211CSE+ operates from a wide supply range of 2.7V to 7V and was designed to allow greater flexibility when interfacing between different voltage signals. The input threshold can be adjusted by the user over a ±100mV range that works to enable interfacing between circuits with different logic levels. The ON resistance is extremely low, typically around 250Ω, so that there is minimal degradation of the signal when the switch is on. The DG211CSE+ features an enable pin that allows the user to enable or disable the switch. The enable pin is especially useful for interfacing between multiple sections of the circuit with differing logic levels or for driving multiple inputs. When the enable pin is disabled, the outputs of the switches are disconnected and the device presents an open circuit. The DG211CSE+ is manufactured with a process that provides excellent noise immunity, thus minimizing the loading of signals when they are switched. The device also offers a wide dynamic range, which makes it well-suited for high-speed signal switching. The device is designed to ensure low static power consumption and can have a short circuit protected output stage. The basic operating principle of the DG211CSE+ is based on its internal biasing circuitry which keeps the FET gate at a given level, regardless of the voltage levels of the signal line and ground. The internal bias voltage of the DG211CSE+ sets the threshold for signal switching and this enables the device to switch between signals with different logic levels. The DG211CSE+ can be used in a variety of application fields such as analog switches, multiplexers, demultiplexers, line drivers, summing amplifiers, signal processors, attenuators, electrical protection, and filtering. In analog applications, the device can be used to switch between multiple signals with different voltage levels and also to provide signal isolation and signal conditioning. The DG211CSE+ can be used as a multiplexer to connect multiple inputs and outputs in a circuit. In digital applications, the device can be used to reduce the number of connections between the logic circuits and to route the signals within a system. The low power consumption of the DG211CSE+ makes it suitable for portable and battery operated applications. The device can also be used for switching between different signals that come from other systems. The DG211CSE+ offers excellent noise immunity and a wide dynamic range which makes it attractive for high-speed switching applications. The device also features short-circuit protection which makes it more reliable in certain applications. In conclusion, the DG211CSE+ is a versatile device that can be used in a wide variety of interface applications. Its low power consumption, wide dynamic range and low ON resistance, combined with its integrated enable pin, make it an excellent choice for powering, switching and isolating signals between different logic levels. The device’s excellent noise immunity and short-circuit protection also make it suitable for high-speed switching applications.
