REF191ESZ-REEL Typical application Circuitry

REF191ESZ-REEL

The REF191ESZ-REEL chip is a precision voltage reference part, widely utilized across various industries for its stability and accuracy in providing a fixed reference voltage. This type of component is crucial in many electronic applications, especially those requiring precise voltage regulation, such as data conversion, power supply control, and measurement systems.

Application Scenarios:

The REF191ESZ-REEL finds its place in numerous settings, from industrial control systems, precision measurement instruments, to battery-powered devices. Because of its great accuracy and low power consumption, it is especially well suited for remote and portable sensing applications.

Parameter Characteristics:

This chip boasts a low temperature coefficient, ensuring its output voltage remains stable over a wide temperature range. It also has a low dropout voltage, which enables precise regulation even in situations where the supply voltage and output voltage are nearly equal. Its precision and stability are further enhanced by a low output noise, making it ideal for sensitive electronic applications.

Specific Circuit Connection for Battery-Powered Sensor Application:

- Choosing the Correct Operating Voltage: Begin by identifying the sensor's required reference voltage. The REF191ESZ-REEL can provide a stable 2.5V, which is common for many sensors.

- Power Supply Considerations: Connect the REF191ESZ-REEL's V_IN pin to a clean, regulated power source that exceeds the dropout voltage of the chip. To prevent damage, make sure the power supply voltage does not exceed the REF191ESZ-REEL's maximum input voltage rating.

- Decoupling Capacitor for Stability: Place a ceramic decoupling capacitor (0.1µF) close to the REF191ESZ-REEL's V_IN pin. This minimizes noise and ensures stable operation, particularly in noisy environments.

- Connecting the Output: Route the REF191ESZ-REEL's V_OUT pin to the sensor's reference voltage input. This connection provides the sensor with a precise and stable voltage for accurate readings.

- Grounding Procedures: Verify that the ground plane of the system is connected to the GND pin of the REF191ESZ-REEL. To reduce noise and improve the reference voltage's overall stability, a strong grounding plan is essential.

- Load Considerations: In circuit design, keep in mind the REF191ESZ-REEL's capability to drive loads. Make sure the current the sensor draws doesn't go over the REF191ESZ-REEL's maximum output current limit.

Design Considerations:

When integrating the REF191ESZ-REEL into your circuit, consider the power supply quality, environmental conditions, and potential loading effects on the output voltage. Ensuring the input voltage is within specified limits and adequately decoupling the supply line will significantly impact the performance. Additionally, account for thermal considerations, as operating temperature can influence the voltage reference stability.

In conclusion, the REF191ESZ-REEL serves as a versatile and reliable component for ensuring voltage precision across various applications. By meticulously planning your circuit design around the REF191ESZ-REEL, focusing on supply stability, decoupling strategies, and proper loading, you can harness its full potential to achieve accurate and stable voltage reference in your electronic designs.
