Switches offer guaranteed latch-up prevention and low charge injection, leakage

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, claim to 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.

The ADG5212 and ADG5213 are packaged in a 4 mm × 4 mm 16-lead LFCSP 16-lead TSSOP and are available now. Each device is priced at $2.18 each in 1,000 quantities.
