22V latch-up proof quad switches from
ADI for industrial and automotive apps
Analog Devices, Inc. has introduced the ADG5212 and ADG5213
high-voltage, latch-up proof quad switches that offer guaranteed
latch-up protection for industrial, instrumentation, and
automotive applications operating at up to ±22 V.
Latch-up, an undesirable high-current state that persists
until the power supply is turned off, can lead to device
failure. The new products, which contain four independent
SPST (single-pole, single-throw) switches, achieve the lowest
charge injection (0.07 pC) and 400 pA max leakage.
Main features of ADG5212 and ADG5213 series are:
1.It has 3-pF off capacitance and 435-MHz -3dB bandwidth,
the lowest charge injection (0.07 pC @ 0 V) and max leakage
(400 pA @ 125 °C) performance.Due to this, it is suitable
for data acquisition and sample-and-hold applications, where
low glitch and fast settling time are required. Low leakage
is an advantage in audio and video signal routing where
high accuracy and resolution are important.
2. These switches operate at high voltage and achieve 2.5
kV HBM and ESD Performance.
3.Attains a 2.5 kV HBM (human body model) ESD rating, which
helps shield equipment from excess current and eliminates
the need for designers to install additional protection
circuitry.
4.Trench isolation between the N-channel and P-channel transistors
of each CMOS switch provides guaranteed latch-up protection.
5.Operate from ±9 V to ±22 V in applications
where the analog signal is bipolar and from +9 V to +40
V in applications where the analog signal is unipolar.
6. Operate equally well in both directions when ON and has
an input signal range that extends to the power supplies.
In the OFF condition, signal levels up to the supplies are
blocked. The switches exhibit break-before-make switching
action for use in multiplexer applications.
The ADG5212 and ADG5213 switches are the additions to ADI's
switch and multiplexer protection products portfolio, which
also includes the ADG5412 and ADG5413 low Ron, 8-kV ESD
(electrostatic discharge) latch-up proof quad switches.
