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