MUX708-Q1 개요
An analog multiplexer is a device that selects one of several analog input signals and forwards it to a single output. In the hierarchy of signal routing components, an analog multiplexer falls under analog switches and multiplexers, which are part of the broader category of interface ICs. These components are essential in data acquisition systems, where multiple sensors need to share a single ADC input, and in automotive body control modules for routing signals from various switches and sensors.
Key features of the MUX708-Q1 include AEC-Q100 qualification for automotive applications, with device temperature grade 1 (-40°C to 125°C ambient operating temperature). It is latch-up immune and has HBM classification level H1C and CDM classification level C3. The device supports 1.8V logic, enabling direct interface with low-voltage microcontrollers without level shifters. Its low on and off leakage currents and ultra-low charge injection make it suitable for precision analog signal routing.
The MUX708-Q1 is built on a robust architecture that ensures reliable operation in harsh automotive environments. The low on-resistance minimizes signal attenuation, while the wide supply range allows operation in 12V and 24V automotive systems. The device's bidirectional capability allows it to pass signals in either direction, making it versatile for both multiplexing and demultiplexing applications.
Typical applications include automotive battery management systems, where it routes voltage and temperature sensor signals to a central ADC, and infotainment systems for audio signal routing. It is also used in industrial process control for sensor multiplexing and in test equipment for signal routing.
When designing with the MUX708-Q1, ensure that the supply voltages are within the specified range and that the signal pins do not exceed VSS or VDD. Proper decoupling capacitors on the supply pins are recommended to maintain signal integrity.

설계 노트
The MUX708-Q1 can operate from a single supply (4.5V to 44V), dual supplies (±4.5V to ±22V), or asymmetric supplies. Ensure that the supply voltages are within the specified range and that the signal pins do not exceed VSS or VDD. For single-supply operation, connect VSS to GND. Proper decoupling capacitors (0.1µF and 10µF) should be placed close to the VDD and VSS pins to maintain stable operation.
For optimal performance, place the MUX708-Q1 close to the signal sources and the ADC to minimize trace length and parasitic capacitance. Use a solid ground plane under the device to reduce noise. Keep analog and digital signals separated to avoid crosstalk. The 16-TSSOP package has a thermal pad; connect it to the ground plane for improved thermal performance.
Avoid exceeding the absolute maximum ratings, particularly the supply voltage and signal pin voltages. Ensure that the address pins (A0, A1, A2) are properly driven to valid logic levels to prevent unintended channel selection. The enable pin (EN) must be high to enable the device; if not used, tie it to VDD. Also, be aware of the on-resistance variation with temperature and supply voltage, which can affect signal accuracy.
