DG417BDQ-T1-E3 is a single analog switch IC (Integrated Circuit) manufactured by Texas Instruments. This IC is a low-saturation, low-on-resistance CMOS (Complementary Metal-Oxide Semiconductor) analog switch which can switch analog and digital signals with low noise and low off-state current. Application FieldThe DG417BDQ-T1-E3 is well-suited for use in a range of applications demanding increased performance, including medical measurements, audio systems and audio/video switching, computer system switching, digital communications, telecom and instrumentation systems. The device\'s low-saturation voltage and low off-state current make it ideal for battery-powered portable devices in which ultra-low power dissipation is essential.Working PrincipleThe DG417BDQ-T1-E3 is a single analog switch IC with a low-saturation voltage and low-off-state current which can switch analog and digital signals with low noise and low off-state current. It uses a single CMOS process to achieve the best performance. The device can be used as a single switch, multiplexer, demultiplexer or complex combinational logic functions in both low and high speed applications.The device can be controlled via a TTL or CMOS logic inputs. When the control inputs are biased low to high, a positive voltage applied to the switch is greater than the off-state voltage and the switch will be turned on. When the control inputs are biased high to low, the voltage applied to the switch is lower than the off-state voltage and the switch will be turned off.The DG417BDQ-T1-E3 has two outputs, which allow it to be used as a muiplexer or demultilpexer. The circuit utilization is similar to that of a multiplexer, however, the DG417BDQ-T1-E3 can be used as a cmplex combinational logic function with the two outputs allowing more flexibility.The device also has an open drain output which can provide a pull-up current to the output of the switch. This feature allows the output of the device to remain open when the input voltage is below the different threshold set by the off-state voltage.The DG417BDQ-T1-E3 utilizes a low-power CMOS process to minimize power dissipation, making it ideal for battery-powered portable devices. It also features a high-frequency switch, providing increased flexibility for applications which require a fast switching speed.In addition, the device has disable inputs which allow the device to be disabled when a voltage is applied to the input. This feature allows a system designer to temporarily turn off the device in order to save power or allow for system maintenance without having to remove the device from the circuit.Overall, the DG417BDQ-T1-E3 provides a single, low-saturation, low-on resistance analog switch which is ideal for applications which demand increased performance including medical measurements, audio systems and audio/video switching, digital communication, telecom and instrumentation systems. The device’s low-saturation voltage and low off-state current make it an excellent choice for battery-powered portable devices in which low power dissipation is essential.
