Product Description

The REF200AU/2K5E4 integrates a precision REF200AU current source and a 2K5E4 sensor interface, designed for reliable signal conditioning in industrial automation and process control. This dual current mirror IC supports two independent current outputs (100 µA to 2 mA range) with ±0.5% accuracy, enabling direct interfacing with resistive sensors or transducer modules. It operates at 4.5V to 40V supply voltage and -40°C to +125°C, ensuring stability in harsh environments. The device lacks built-in communication interfaces, requiring external circuitry for digital integration. Key advantages include low drift (±20 ppm/°C) and high output impedance (>1 GΩ), while its limitation lies in minimal onboard protection for overvoltage/overcurrent. Typical detection ranges span 0-10 kΩ sensor resistance with resolution down to 5 mV/Ω. No battery or display components are integrated.
