ADG5401

Data Sheet FEATURES Latch-up immune under all circumstances Human body model (HBM) ESD rating: 8 kV Low on resistance: 6.5 Ω ±9 V to ±22 V dual-supply operation 9 V to 40 V single-supply operation 48 V supply maximum ratings Fully specified at ±15 V, ±20 V, +12 V, and +36 V VDD to VSS analog signal range APPLICATIONS High voltage signal routing Automatic test equipment Analog front-end circuits Precision data acquisition Amplifier gain select Industrial instrumentation Relay replacement GENERAL DESCRIPTION The ADG5401 is a monolithic industrial, complementary metal oxide semiconductor (CMOS) analog switch containing a latchup immune single-pole/single-throw (SPST) switch. The switch conducts 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 ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. The latch-up immune construction and high ESD rating make these switches more robust in harsh environments.

Trench isolation guards against latch-up. A dielectric trench separates the P channel and N channel transistors, thereby preventing latch-up even under severe overvolt...
