REF200AUE4 Typical application Circuitry

REF200AUE4

The REF200AUE4 is a versatile and precise integrated circuit (IC) known for its dual current source and current sink capabilities. This IC finds applications in various scenarios, including precision current regulation, current sensing, and as a building block in more complex analog circuits. Its key parameters and features include.

1. Dual Current Sources: The REF200AUE4 provides two matched current sources, each capable of delivering a precise 100 µA current, making it suitable for precision applications.

2. Wide Supply Voltage Range: It operates effectively across a broad supply voltage range, typically from +10V to +40V, catering to various circuit designs.

3. High Accuracy: The precision current outputs are highly accurate, with a typical initial accuracy of ±0.5% and a low temperature coefficient, ensuring reliable performance across temperature variations.

4. Low Temperature Drift: The temperature drift is minimized, enhancing the stability of the current outputs over a wide temperature range.

5. Versatile Functionality: Besides being used as a current source, it can function as a current mirror, current sink, or a floating current source, offering flexibility in circuit design.

Application Scenario: Precision Current Source for Sensor Calibration:

In this scenario, the REF200AUE4 is used to provide a stable current source for calibrating sensors in an instrumentation setup. The detailed circuit connection includes:

- Power Supply Connection: The V+ pin of the REF200AUE4 is connected to a stable power supply within the IC's operating range, typically around +15V for optimal performance.

- Current Source Output: The Iout1 and Iout2 pins, each providing 100 µA, are utilized as the precision current sources. One of these pins is connected to the sensor's calibration input.

- Grounding: The GND pin is connected to the system's ground. This ensures the stability of the output current and minimizes noise interference.

- Load Connection: The load (sensor) is connected in series with the current output pin (Iout1 or Iout2). It's crucial to ensure that the voltage across the sensor doesn't exceed the compliance voltage of the REF200AUE4.

- Adjustment for Desired Current: If a current other than 100 µA is required, an external resistor can be connected in parallel with the Iout pin to adjust the output current accordingly.

Design Considerations:

- Stable Power Supply: A consistent and stable power supply is essential to maintain the accuracy of the current sources.

- Thermal Management: Given the REF200AUE4's low temperature drift, operating within the specified temperature range is crucial for maintaining precision.

- Compliance Voltage: Ensure that the voltage across the load does not exceed the REF200AUE4's compliance voltage to prevent damage to the IC.

- Load Resistance: The load resistance should be chosen such that it allows the current to flow within the IC's specifications without causing an excessive voltage drop.

In conclusion, the REF200AUE4 is a highly accurate and versatile IC, ideal for precision current sourcing applications like sensor calibration. Its dual current sources, coupled with a wide supply voltage range and high accuracy, make it a reliable choice in various electronic designs.
