December 12, 2013 – Analog Devices (www.analog.com, NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, announced four new 8-kV ESD (electrostatic discharge) switches that guarantee latch-up protection for high-voltage industrial applications operating at maximum ±22Vds or +40Vss.

ADI's high-voltage ADG5401, ADG5421, ADG5423, and ADG5419 single and dual switches have been newly added to the latch-up protection product family, which now enables configurations ranging from SPST×1 switches to 32:1 multiplexers. Latch-up refers to a phenomenon where an unintended high-current state persists until power supply is shut down, which can cause device malfunction.

Each CMOS switch product features trench isolation between N-channel and P-channel transistors, providing guaranteed latch-up protection under all conditions. Additionally, these switch products achieve an industry-leading 3-kV HBM (human body model) ESD rating. These characteristics not only enhance the shielding effect of equipment against excessive current but also eliminate the need for designers to install additional protection circuits. Furthermore, ADI's new switch products provide low R(on) flatness and performance, minimizing temperature variations and feedback resistance while optimizing gain switching.
