ISL32490EIUZ is a current loop transceiver designed to provide an interface between digital circuitry and current loop sensors and actuators. The transceiver provides a compact, low-power solution and operates in systems ranging from 5V to 15V supply voltages. The ISL32490EIUZ provides flexibility, allowing the user to configure the transceiver to meet the needs of their application. The transceiver is offered in two target applications and can be operated in four operating modes.
Features
The ISL32490EIUZ device offers a number of features that make it an ideal solution for a variety of current loop transceiving applications. These include:- High common-mode rejection ratio
- ±7V fault protection
- Flexible power supply range
- Low power consumption
- Four operating modes (receive only, transmit only, write-to-read, and write-to-write)
Application Fields
The ISL32490EIUZ can be used in a range of applications including industrial and process control, medical instrumentation, consumer electronics, and automotive applications. It is particularly well suited for applications that require a high level of common-mode rejection or require low-power operation. Examples of such applications include:- Current loop sensor interfaces
- Industrial process control
- Medical instrumentation
- Open-loop test/calibration circuits
- Consumer electronics
- Heating, ventilation and air conditioning (HVAC)
- Automotive
Working Principle
The ISL32490EIUZ transceiver is based on a differential amplifier architecture which provides high common-mode rejection. Its broad operating range of 5V to 15V makes it suitable for many applications. The device can be operated in four modes: receive mode, transmit mode, write to read mode, and write to write mode.Receive Mode
In receive mode, the transceiver is used to interface a digital system (microprocessor, FPGA, etc.) with a current loop actuation system. A current loop is a two-wire data transmission system where the actuation commands are sent as a continuous current (rather than as a packet of voltages/waves). The transceiver converts the current loop commands into voltage or logic signals which can then be read by the digital system.Transmit Mode
In transmit mode, the transceiver is used to convert digital signals into current loop commands. The user configures the transceiver to provide the desired current loop output range, which can then be used to drive a current loop actuation system.Write-to-Read Mode
In write-to-read mode, the transceiver can be used to interface a digital system with a current loop sensor. The user configures the transceiver to provide the desired input range, which can then be used to read a current loop signal.Write-to-Write Mode
In write-to-write mode, the transceiver can be used to send and receive current loop commands. The user configures the transceiver to provide the desired output range, which can then be used to send current loop commands, while the same transceiver is used to read incoming current loop signals.
