ANALOG DEVICES’ SWITCHES OFFER GUARANTEED LATCH-UP PREVENTION, LOW CHARGE INJECTION AND LOW LEAKAGE

Norwood, MA (05/16/2011) - Analog Devices, Inc. (ADI), today 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 industry’s lowest charge injection (0.07 pC) and 400 pA max leakage.

The ultra-low charge injection of the new switches makes them 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. The ADG5212 and ADG5213 switches are the latest 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.

ADG5212 and ADG5213 Switches Operate at High Voltage and Achieve 2.5 kV HBM and ESD Performance

• 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.

• Trench isolation between the N-channel and P-channel transistors of each CMOS switch provides guaranteed latch-up protection.

• 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.

• Features 3-pF off capacitance and 435-MHz -3dB bandwidth, the industry’s lowest charge injection (0.07 pC @ 0 V) and max leakage (400 pA @ 125 °C) performance.

• 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.
