Analog Devices’ ADG54xx single and dual switches offer guaranteed latch-up protection for industrial, instrumentation and process control applications.

NORWOOD, Mass. — (BUSINESS WIRE) — December 9, 2013 — Analog Devices, Inc. (NASDAQ: ADI) introduced today four 8kV ESD (electro-static discharge) switches that guarantee latch-up prevention in high-voltage industrial applications operating up to ±22 Vds or +40 Vss. ADI’s high-voltage ADG5401, ADG5421, ADG5423 and ADG5419 single and dual switches are new additions to the latch-up immune family, which now includes configurations from SPSTx1 switches to 32:1 multiplexers. Latch-up, an undesirable high-current state that persists until the power supply is turned off, can lead to device failure.

Trench isolation between the N-channel and P-channel transistors of each CMOS switch provides guaranteed latch-up immunity under all conditions. The switches also achieve an industry best 8-kV HBM (human body model) ESD (electrostatic discharge) rating. Both features help shield equipment from excess current and eliminate the need for designers to install additional protection circuitry. The new switches also have low Ron flatness and performance which minimizes temperature variation and feedback resistance and optimizes gain switching.
