ADG823BRMZ

The ADG823BRMZ is a monolithic CMOS analog multiplexer/demultiplexer manufactured by Analog Devices, Inc. It is designed to select one of four differential signals and route it to either the positive (non-inverting) or the negative (inverting) input of the multiplexer. The ADG823BRMZ can be used to switch between two pairs of analog signals, thus making it an ideal choice for applications requiring signals to be switched between different locations.

The ADG823BRMZ employs advanced CMOS processing techniques to provide low power consumption and excellent temperature stability. The analog multiplexer/demultiplexer contains three low-voltage CMOS switches that are controlled by two independent enable pins (EN1, EN2). The enable pins can be operated in complementary or non-complementary modes, allowing very flexible signal routing configurations.

The ADG823BRMZ is designed to provide high-frequency performance with excellent isolation and low crosstalk between channels. The multiplexer/demultiplexer uses a combination of a dielectric of polyimide and low-impedance ground for improved signal isolation. The analog switches include ESD protection structure that can guard against electrostatic discharge (ESD) induced voltages.

The ADG823BRMZ is available in a 10-pin TSSOP package and is ideally suited for applications like industrial process control, instrumentation, automotive, and medical systems. It can be used to multiplex analog signals, route multiplexed signals from one place to another, and route signals to or from different nodes or integrated circuits. The application range of the ADG823BRMZ spans from low to high frequencies and it is ideal for applications with RF, IF, and high-speed signals.

The working principle of the ADG823BRMZ is based on its on-chip select pins (EN1 and EN2). The select pins are used to control the CMOS switches, allowing one of four differential signals to be routed to either the positive or the negative input of the multiplexer. The switches are designed to be operationally transparent, meaning that the signals passing through the multiplexer are unaffected by the switching process. The ADG823BRMZ also includes an enable input pin, which can be used to enable and disable the multiplexer.

In summary, the ADG823BRMZ is an analog multiplexer/demultiplexer designed for use in industrial process control, instrumentation, automotive, and medical systems. It is designed to provide superior performance across a wide range of frequencies and is capable of switching between two pairs of analog signals. The working principle is based on its two independent enable pins (EN1, EN2), which control the CMOS switches and allows one of the differential signals to be routed to either the positive or the negative input of the multiplexer.
