HJU0420 is a high-temperature precision 4-20mA/0-20mA current loop transmitter made using thick film integrated circuit technology. It includes a precision reference voltage source, two precision wideband operational amplifiers, and multiple precision matched resistor pairs. It can convert an input voltage of 0-2.5V (0-5V) into an output current of 4-20mA (or 0-20mA). It has advantages such as selectable output current, strong dynamic output capability, and a wide frequency range. The improved thick film integration process avoids the defect of 'purple spots' that can easily form during gold-aluminum bonding at high temperatures, enhancing the long-term reliability of the device in high-temperature environments. It uses a single power supply with reverse polarity protection at the power supply and output ends, and surge protection at the signal output end. The power supply range is VCC = +13V to +36V, covering the aviation 28V power supply range. The device's maximum operating temperature reaches 175°C and can be widely used in signal transmission systems.
