REF02BU Typical application Circuitry
The REF02BU is a precision voltage reference chip produced by Texas Instruments. This chip delivers a fixed 5V output with high precision, serving as a reference voltage for various applications in circuit design.
Highlighted attributes of the REF02BU are:
1. Precision Voltage Output: The REF02BU provides a steady 5V output with an impressive accuracy of ±0.3% at 25°C.
2. Low Power Consumption: With a typical quiescent current consumption of just 1.4mA, this chip is an eco-friendly option for power-sensitive applications.
3. Low Temperature Coefficient: With a temperature coefficient of typically only 10ppm/°C, the chip maintains its voltage output with minimal variation across a wide temperature range.
4. High Output Current: Capable of delivering up to 10mA output current, the REF02BU is suitable for a variety of load requirements.
The REF02BU can be used in numerous applications, including but not limited to DACs (Digital-to-Analog Converters), ADCs (Analog-to-Digital Converters), precision measurement equipment, and industrial control systems.
Considering the usage in a DAC circuit, the connection of REF02BU can be depicted as follows:
1. Power Input: Connect the power supply to the "V+" pin (Pin 8). This pin is the power supply input and accepts a wide voltage range (7V to 40V).
2. Voltage Reference Output: The fixed 5V reference voltage is provided at the "Vout" pin (Pin 6), which can be directly connected to the reference voltage input of your DAC.
3. Ground Connection: Connect the "GND" pin (Pin 4) to the system ground. The chip's common ground is located on this pin.
4. Capacitor Connection: For stable operation, connect a 0.1uF capacitor between the "Vout" and "GND" pins.
5. No Connection Pins: Pins 1, 2, 3, 5, and 7 have no internal connection and should be left unconnected.
When utilizing the REF02BU in circuit design, you should contemplate:
1. Power Supply: The input voltage must lie within the specified operating range (7V to 40V). An out-of-range voltage can damage the chip or cause incorrect operation.
2. Load Current: Ensure the load connected to the chip doesn't require more than the 10mA maximum output current of the REF02BU.
3. Decoupling Capacitor: Don't forget to place a decoupling capacitor between the output and ground pins to ensure stable operation.
4. Operating Temperature: The chip should be operated within its specified temperature range to maintain precision voltage output.
