The ADG202AKRZ-REEL7 part from Analog Devices Inc. is a member of the Interface - Analog Switches, Multiplexers, Demultiplexers family. It is an integrated circuit (IC) that contains an array of switches and multiplexer/demultiplexer circuits that can be used in a wide range of systems. By using this IC, engineers can improve system performance and reduce wasted time in the process of signal routing.

The part number of this IC suggests its application field, such as high-speed data transmission, signal routing, signal conditioning, as well as interfacing low power devices. It has 16 single-pole/single-throw (SPST) switches, 2 4:1 multiplexer/demultiplexer circuits and a power control circuit for each switch. It is designed to be used in a variety of circuits, and many engineers are able to include it into their designs.

The operating voltage of the IC is from 3.0 to 18 Volts and its ultimate isolation voltage is rated up to +/-60 Volts. Additionally, the power consumption of each switch is 1.2 mA, with a maximum off-state leakage current of +/-100nA. The internal multiplexers have a resistance of around 50Ω, with a propagation delay time of 4 µs.

The ADG202AKRZ-REEL7’s switches can be operated using TTL voltage levels, which enables designers to connect the IC directly to digital circuits. One of the terminals of each switch is connected to a common bus, while the other terminal is directly connected to the multiplexer/demultiplexer circuits. The signals to be routed are supplied to the common bus, while an address selector creates the connection between the common bus, the output, and the appropriate switch.

The IC is able to route signals rapidly and in a controlled manner. The internal power control circuit prevents leakage currents and discharges of the capacitive loads. Additionally, the logic level of the output is different from the analog level, allowing the IC to be applied to both digital and analog circuits, as long as the voltage difference between the two parts is within the specified limits.

In summary, the ADG202AKRZ-REEL7 IC is a versatile Analog switch multiplexer/demultiplexer IC that is suitable for a variety of applications. It can operate using TTL voltage levels, and its off-state leakage current is very low. With a power control circuit built in, the IC provides an excellent signal routing solution for engineers.
