The DG390ACJ+ is a precision, dual, high-performance analog switch designed by Maxim Integrated to cater to a wide range of applications requiring high-speed switching and low on-resistance. This device is engineered to provide superior performance in systems where low leakage currents and fast switching are paramount.

Featuring a dual SPDT (Single Pole Double Throw) configuration, the DG390ACJ+ offers flexibility in signal routing for analog and digital signals. Each switch can conduct equally well in both directions when on, and each has an input signal range that extends to the power supply rails.

With its low on-resistance (<35 ohms), the DG390ACJ+ ensures minimal signal attenuation, making it an ideal choice for audio and video signal routing, data acquisition systems, and sample-and-hold circuits. The low charge injection characteristic of the device preserves signal integrity by minimizing distortion during switching, thereby enhancing the overall performance of the system it is integrated into.

The DG390ACJ+ operates over a wide voltage range from ±4.5V to ±18V or from a single supply of +9V to +36V, providing design flexibility for both bipolar and unipolar power supply systems. This versatility makes it suitable for a variety of industrial, communication, and instrumentation applications.

Additionally, the switch features TTL/CMOS-compatible logic inputs, which simplify the interface with digital circuitry. The high off-isolation and low crosstalk of the DG390ACJ+ ensure that signals are kept separate and noise-free, which is critical in high-performance, multi-channel systems.

Maxim Integrated's commitment to quality and reliability is evident in the DG390ACJ+, with its robust latch-up performance and ESD tolerance. Packaged in a standard 16-pin PDIP (Plastic Dual In-line Package), the device is also easy to incorporate into existing designs without the need for complex board changes.

In summary, the DG390ACJ+ from Maxim Integrated stands out as a reliable and efficient solution for designers looking to optimize their high-speed, precision switching applications.
