DG387ACJ is a quad single-pole/single-throw, analog signal switch. It offers low on-resistance and low charge injection which makes it ideal for signal multiplexing applications. DG387ACJ is designed specifically for signal switching applications, with excellent AC and DC characteristics. The device is capable of handling signal frequencies up to 20 MHz, with low distortion and low signal attenuation.

The core feature of the DG387ACJ is its quad-channel SPST configuration, allowing it to switch four independent signals in a single integrated circuit. Each channel can be controlled via logic-level or TTL control signal, with an on-resistance of 0.50ohm typical. This makes it particularly suitable for use in sampling and switching applications, such as data acquisition systems, analog-to-digital conversion, and signal conditioning circuits. Additionally, the DG387ACJ is capable of operating over a wide operating temperature range (−55 to +125 °C).

The DG387ACJ is highly reliable and robust, with a power dissipation rating of 150 mW typical. The device features ESD protection on all control pins, as well as latch-up and overvoltage protection, making it suitable for use in harsh environments. Its 3 V logic compatible control pins are also compatible with various microcontroller/microprocessor systems.

The DG387ACJ can be used as a multiplexer, demultiplexer, analog switch, or logic switch in various applications. As an analog switch, it can be used to connect an output signal to one of several inputs, or vice-versa. When used as a multiplexer, the DG387ACJ can switch between multiple input signals to a single output. Similarly, it can be used as a demultiplexer, connecting a single input to one of several outputs. It can also be used as a logic switch, where the input signals are connected to the output based on the logic state of the control pins.

The DG387ACJ is an ideal choice for a wide range of signal switching applications, offering excellent performance and stability over a wide range of environmental and operating conditions. Its small form factor and low power consumption make it an ideal solution for embedded and mobile applications.
