Analog Devices offers a broad portfolio of robust ±15 V switches and multiplexers that are used in a wide range of applications where system reliability is critical, including industrial and instrumentation, medical, consumer, communications, and automotive systems. Leveraging the patented iCMOS manufacturing process technology, ADI's array of switches and multiplexers offers industry leading performance in very small form factors to enable board area space savings.

Automatic Test Equipment Applications

For ATE applications with single-ended or differential inputs, ADI offers a choice of multiplexers with single four, eight, and sixteen channels or differential four and eight channels. The ADG1406 is a ±15 V 16:1 multiplexer, and the ADG1407 is a differential 8:1 multiplexer. Both offer low on resistance of 8 Ω with <1 Ω on-resistance flatness over the full signal range and are available in space-saving 5 mm × 5 mm LFCSP packages.

Medical Applications

In medical applications such as line-powered ECG, where the requirements are generally for low R_ON, dual-supply operation switches, the ADG1411 (4 × SPST) offers superior on resistance of 1.5 Ω and R_ON flatness of 0.28 Ω over the full signal range. This level of performance assists in minimizing signal loss and distortion of the signal through the switch—especially important when switching gains for op amps. The ADG1411 is available in 4 mm × 4 mm LFCSP packages, suitable for both portable and benchtop systems.

Industrial Applications

Industrial design engineers require analog switches that support faster sampling, increased performance, lower power dissipation, and a smaller footprint. The ADG1201 SPST and ADG1219 SPDT switches meet these requirements by offering ultralow capacitance, charge injection, and leakage at ±15 V operation. Both have <1 pC charge injection and low leakage of <1 nA at 125°C and are available in tiny 6-lead SOT-23 package.
