4-Channel commutator

The DS7800 voltage translator is a monolithic device that provides a gate drive voltage ranging from 10 V to -20 V for JFETs while simultaneously ensuring DTL/TTL logic compatibility. This 4-channel commutator utilizes the 2N4091 to achieve a low channel on resistance of less than 30 ohms and minimal off current leakage.

The DS7800 voltage translator is designed to interface between high-voltage JFETs and low-voltage digital logic systems, making it suitable for applications where signal integrity and compatibility are crucial. Its ability to provide a wide gate drive voltage range allows for effective control of JFETs, which are often used in analog switching and amplification applications.

The 4-channel commutator is built around the 2N4091, a JFET known for its low on-resistance characteristics, which is critical in minimizing power loss during operation. The specified on-resistance of less than 30 ohms ensures that the channels can conduct with minimal voltage drop, thereby enhancing the overall efficiency of the circuit. Additionally, the low off current leakage is essential for maintaining the integrity of the signals when the channels are not in use, preventing unwanted interference or crosstalk between channels.

In practical applications, the combination of the DS7800 and the 2N4091 allows for the design of robust and efficient switching circuits that can handle varying voltage levels while maintaining logic compatibility. This makes the circuit well-suited for use in communication systems, data acquisition systems, and other electronic applications where reliable signal processing is required. The DS7800 voltage translator is a monolithic device that provides from 10 V to -20 V gate drive to the JFETs while at the same time providing DTL/TTL logic compatibility. This 4-channel commutator used the 2N4091 to achieve low channel on resistance (<30 ohm) and low off current leakage. 🔗 External reference
