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.
