Key Features

  • Fault and Overvoltage Protection: The ADG438FBRZ can withstand continuous voltage inputs from −40 V to +55 V, protecting both the device and the signal source during fault conditions.
  • Low RON and Fast Switching Times: The device features a low on-resistance of 270 Ω and fast switching times of 250 ns (tON) and 150 ns (tOFF).
  • Break-Before-Make Construction: Ensures that the old channel is turned off before the new channel is turned on, preventing signal overlap.
  • TTL- and CMOS-Compatible Inputs: Compatible with both TTL and CMOS logic levels, making it versatile for various system integrations.
  • Small Charge Injection and Low Crosstalk: Features a small charge injection of 15 pC and low crosstalk of -93 dB @ 100 kHz, reducing signal distortion and noise.

Applications

  • Data Acquisition Systems: Ideal for switching multiple analog signals in data acquisition systems.
  • Industrial and Process Control Systems: Used in industrial settings for reliable signal routing and control.
  • Avionics Test Equipment: Suitable for avionics due to its high reliability and fault protection features.
  • Biometric Identification: Used in biometric identification functions such as fingerprint and iris recognition.
  • Internet of Things (IoT): Facilitates communication between IoT devices like RFID and Bluetooth chips.
  • Data Security: Used in security protection functions like encryption/decryption chips.
