Q: What are the main features of the REF200AU/2K5?
A: The REF200AU/2K5 is a precision dual 100 µA current source and current sink with an integrated current mirror. It provides current accuracy of approximately ±0.5%, a low temperature coefficient of 25 ppm/°C, and a wide compliance-voltage range from 2.5 V to 40 V. Its floating configuration does not require a dedicated power-supply or ground connection, giving designers greater flexibility when creating current-bias and analog circuits. The device is supplied in an 8-pin SOIC package.
Q: What is the REF200AU/2K5 used for?
A: The REF200AU/2K5 is used to generate accurate and stable 100 µA currents for analog circuits. Typical applications include sensor excitation, precision biasing, current mirrors, signal conditioning, instrumentation, and analog circuit testing. Its flexible floating operation is useful in circuits where accurate current sourcing or sinking is required without relying on a conventional ground connection.
Q: Does it have any alternative manufacturer and part number, such as?
A: Yes, alternatives may be available from manufacturers such as Analog Devices and Microchip Technology. However, a true replacement should be selected carefully because the REF200AU/2K5 combines dual 100 µA current sources and sinks, a current mirror, floating operation, and a 2.5 V to 40 V compliance range. Designers should compare current accuracy, temperature coefficient, compliance voltage, output impedance, operating requirements, package, and pin configuration before selecting an alternative.
Q: Is technical support available for this part?
A: Yes. Technical support can include datasheet and pinout information, current-source and current-mirror circuit design, compliance-voltage analysis, temperature-drift evaluation, PCB implementation, and alternative-component assessment. Professional distributors can also assist with specification verification, stock availability, sourcing, and replacement selection for existing designs.
