Connect to the negative voltage rail or system ground. 20 GND Ground pin, also used for power return.4. Pin Function Details:
VDD (Pin 1): This is the positive power supply. The voltage applied to this pin powers the device and is typically connected to +5V or +3.3V. INx (Pins 2-5): These pins are digital control inputs that determine the operation of the switches. When set to a certain logic level (high or low), the corresponding switches select which signal is routed to the output. These control pins determine whether a signal passes from the A side or the B side of the SPDT switch. SxA & SxB (Pins 6-13): These are the signal input/output pins for each switch. These pins allow signals to be passed through the corresponding A or B side depending on the state of the associated INx pin. GND (Pins 14, 19): These are the ground connections for the part. All GND pins should be connected to the common system ground. NC (Pins 15-18): These are not connected and should generally not be used. They are reserved for future configurations or specific application designs. VSS (Pin 19): This pin is the negative power supply or the system ground connection.5. 20 Frequently Asked Questions (FAQ):
Q1: What is the purpose of the ADG1409YRUZ? A1: The ADG1409YRUZ is a quad single-pole double-throw (SPDT) switch designed to route analog signals based on control inputs. It’s often used in audio, video, and communication applications.
Q2: What is the voltage range for VDD? A2: The VDD pin (Pin 1) should be connected to a supply voltage between +2.7V and +5.5V.
Q3: Can I connect the INx pins directly to logic outputs? A3: Yes, the INx pins (Pins 2-5) are designed to be connected to logic-level control signals (usually 0V for low and VDD for high) to control the switches.
Q4: What is the maximum current allowed through the signal paths (SxA and SxB)? A4: The maximum continuous current through any signal path (SxA or SxB) should not exceed 100mA.
Q5: Can the ADG1409YRUZ switch digital signals? A5: Yes, the ADG1409YRUZ can switch both analog and digital signals, but it is optimized for analog signal routing.
Q6: What are the power supply requirements for this component? A6: The component operates with a single power supply voltage, typically between +3.3V and +5V, and should be connected to a ground (GND).
Q7: Is there any limitation on the signal frequency? A7: The ADG1409YRUZ can handle signals up to several MHz, but signal integrity may degrade with very high-frequency signals.
Q8: What are the typical applications for the ADG1409YRUZ? A8: Typical applications include audio signal switching, video switching, signal routing in communication equipment, and test equipment.
Q9: Can the INx pins be left floating? A9: No, the INx pins should not be left floating. They must be connected to a logic level voltage to ensure proper switch operation.
Q10: What happens if I exceed the voltage ratings for VDD? A10: Exceeding the voltage ratings can damage the part and cause it to malfunction or fail completely.
Q11: How should I handle the NC pins? A11: The NC pins (Pins 15-18) should be left unconnected in typical applications.
Q12: Can the ADG1409YRUZ be used in a high-speed digital circuit? A12: While the ADG1409YRUZ can switch digital signals, it is primarily intended for analog signals. For high-speed digital circuits, other parts may be more suitable.
Q13: How do I know if my signal is being passed through? A13: If the INx control pins are set correctly, the signal will be routed from the A side (SxA) or the B side (SxB) of each switch.
Q14: What is the maximum power dissipation for the ADG1409YRUZ? A14: The maximum power dissipation is approximately 500mW at typical conditions.
Q15: Is the ADG1409YRUZ suitable for low-voltage systems? A15: Yes, the ADG1409YRUZ operates with supply voltages as low as 2.7V, making it suitable for low-voltage systems.
Q16: Can the device be used in battery-powered applications? A16: Yes, the ADG1409YRUZ is suitable for battery-powered applications due to its low power consumption.
Q17: What is the on-resistance of the switches? A17: The on-resistance of the switches is typically 10Ω, depending on the voltage supplied to VDD.
Q18: Can I connect the switches in series or parallel? A18: The switches can be configured in series or parallel depending on your application, but the control logic must be carefully considered.
Q19: How should I handle the GND pins? A19: All GND pins (Pins 14 and 19) should be connected to the common ground in the system to ensure proper operation.
Q20: Is there any special handling required for the TSSOP-20 package? A20: The TSSOP-20 package is relatively small and should be handled carefully to avoid mechanical damage during assembly or installation.
