The Analog Devices ADG4612BRUZ-REEL7 is a quad SPST power-off protection switch IC with 5V/12V input voltage ratings. It is composed of four single-pole-single-throw switches that provide controlled signal path switching, while preserving circuit integrity during power-off states. With low input leakage, this IC is suitable for use in systems with dual power supplies. The device is very small, with a maximum height above the board of only 1.5mm, making it highly suitable for portable and space-constrained applications. The IC utilizes CMOS process technology for low power dissipation, making it highly efficient, while its 100 Ohm switch on-resistance makes it ideal for signal switching applications. It features an on-chip temperature-compensated band gap reference, improving accuracy and reliability. The device also offers high electrostatic discharge protection, making it well-suited for environments with higher levels of noise and vibration.
