Choosing the Correct Switch or Multiplexer for Your Application - 2

Analog Devices offers a large range of switches and multiplexers, covering single to multiple switch elements with various signal ranges, in a variety of packages to best suit customer application needs. Deciding on the best switch or multiplexer for your application can, therefore, be a difficult task. The simplest switch (single-pole, single-throw—SPST ) will connect or disconnect an analog signal when a digital input signal is applied. Increasing the number of throws will then allow the switching of one of many inputs to one single output. Some switches offer different transient...

• Bandwidth—the frequency at which the output is attenuated by 3 dB. • Isolation—a measure of the unwanted signal coupling through an off switch. Other specifications that may need to be considered: • Crosstalk—a measure of the unwanted signal that is coupled through from one channel to another as a result of parasitic capacitance. New: Additional Protection Requirements Do you require a switch/mux optimized for robustness and protection with latch-up proof, power-off protection (with overvoltage), or overvoltage protection? • Latch-up proof means that latch-up will not occur regardless of...

New: ∙22 V Switches and Multiplexers with Guaranteed Latch-Up Prevention Analog devices offers a new range of switches able to guarantee latch-up prevention in high voltage industrial applications operating up to ±22 V. These switches are designed for instrumentation, automotive, and other harsh environments that are prone to latch-up, which is an undesirable high current state that can lead to device failure and persist until the power supply is turned off. A partial list of our high voltage switches and multiplexers with guaranteed latch-up prevention can be seen in the tables below....

New: ±5 V Power-Off Protection Switches with Overvoltage Protection Analog Devices offers two new power-off protection switches that guarantee an off state in the absence of a power supply. Unlike standard switches, which can be either open or closed when no power supply is present, the ADG4612 and ADG4613 power- off protection switches ensure an off state, which prevents potentially damaging current from flowing to circuit boards used in data communications, communications infrastructure systems, and other sensitive equipment. The guaranteed off-state feature is particularly useful in...

Crosspoint Switches Are Ideal for Multi-I/O Applications For those applications with a large number of input and output signals, it is important to be able to flexibly switch multiple inputs to multiple outputs. The ADG2128 crosspoint family offers CMOS switch matrices with sizes ranging from 8 × 8 to 12 × 8 and are packaged in an incredibly small 5 mm × 5 mm LFCSP package. ADI’s unique technology ensures that this tiny solution also delivers best-in-class parametric performance with up to 300 MHz bandwidth, –65 dB off isolation (5 MHz), –70 dB crosstalk performance (5 MHz), and only 35 Ω...
