ADG709BRUZ-REEL7 Visão geral
An analog multiplexer is a device that selects one of several analog input signals and forwards it to a single output. In this case, the ADG709 is a differential 4:1 multiplexer, meaning it handles four differential signal pairs and routes one pair to the output. This is essential in applications where signal integrity and minimal distortion are critical, such as data acquisition systems, communication systems, and audio/video switching. The multiplexer acts as a switch, connecting the selected input to the output while providing high isolation from unselected channels.
Key features of the ADG709BRUZ-REEL7 include bidirectional analog channels, glitch-free switching, and a wide operating temperature range of -40°C to +125°C. The low on-resistance of 4.5 ohm ensures minimal signal attenuation, while the CMOS construction provides low power consumption. The device is available in a 16-lead TSSOP package, which is compact and suitable for space-constrained designs. The EN pin allows for easy power-down or channel disabling, enhancing system flexibility.
Technically, the ADG709 uses a CMOS process that provides low leakage currents and high switching speeds. The differential architecture improves noise immunity by rejecting common-mode noise, which is critical in industrial and communication environments. The device also features break-before-make switching, preventing momentary shorting of channels during transitions. This ensures glitch-free operation, which is vital in precision measurement and audio applications.
Typical applications include data acquisition systems, communication systems, relay replacement, audio and video switching, and battery-powered systems. In data acquisition, the ADG709 can route multiple sensor signals to a single ADC, reducing component count and cost. In audio systems, it enables seamless switching between multiple audio sources without audible clicks or pops.
When designing with the ADG709, ensure that the analog input signals remain within the supply rails to avoid forward-biasing the internal diodes. Additionally, proper decoupling of the power supply pins with 0.1 uF capacitors is recommended to minimize noise. The EN pin can be used to place the device in a low-power state when not in use, conserving battery life in portable applications.

Notas de projeto
The ADG709BRUZ-REEL7 operates from a single supply of 1.8 V to 5.5 V. Ensure the supply voltage is within this range and is adequately decoupled with a 0.1 uF ceramic capacitor placed close to the VDD pin. The device consumes very low power, but proper decoupling minimizes noise and ensures stable operation. According to the ADG708/ADG709 datasheet, the supply current is typically in the microamp range, making it suitable for battery-powered applications.
For optimal performance, place the ADG709BRUZ-REEL7 close to the signal sources and ADC to minimize trace lengths and reduce parasitic capacitance. Use a solid ground plane and route differential signal pairs symmetrically to maintain common-mode rejection. Add 0.1 uF decoupling capacitors on the VDD pin and optionally on the EN pin. According to the ADG708/ADG709 datasheet, proper layout is essential for high-speed switching applications.
Ensure that the analog input signals do not exceed the supply rails (VDD and GND) to avoid forward-biasing the internal ESD diodes, which can cause latch-up or damage. The ADG709BRUZ-REEL7 is a CMOS device, so unused inputs should be tied to a defined voltage to prevent floating nodes. Also, verify that the EN pin is properly driven; when EN is low, all channels are off. According to the ADG708/ADG709 datasheet, the absolute maximum ratings should not be exceeded.
