REF01CN8 Application Field and Working Principle

REF01CN8 is an integrated integrated voltage reference developed by Texas Instruments, which is a member of the Precision References (PMIC - Voltage Reference) family. It is an 8-pin, temperature-stable zener diode reference device with improved performance, accuracy and temperature stability, making it ideal for a variety of applications.

Application Field

The REF01CN8 voltage reference can be widely used in a variety of applications, such as battery-powered instrumentation and portable medical equipment, automotive systems, industrial and telecoms products. It is also suitable for applications requiring system accuracy or small size.

Performance

The REF01CN8 offers precise outputs of 5 V, 2.5 V and 1.25 V, with temperature coefficients as low as 10 ppm / ° C, and extremely low output noise. It also has a stability of 0.1% over the operating temperature range and an excellent temperature coefficient of 11 ppm / °C and a temperature gradient of 1.2 mV / °C. With these features, it is an ideal choice for accurate, low-noise reference for signal conditioning, battery charging and bias reference applications.

Function

The REF01CN8 is a voltage reference implemented in an 8 lead surface mount plastic package, it can provide powerful, precise and regulated output voltages. It has an Output Enable (OE) pin, which when pulled low will turn off the output voltage and limit its quiescent current to a very low level. It also offers precision voltage reference, low temperature coefficient, and low temperature drift, making it suitable for a variety of applications.

Working Principle

The REF01CN8 consists of a temperature stable zener with a gain stabilizing amplifier, which is connected in a negative feedback loop. The zener diode is maintained at a constant voltage, while the gain setting amplifier adjusts the current over a wide temperature range. The output is internally regulated and uses a temperature stable zener, meaning it has reliable temperature stability and accuracy.

The REF01CN8 voltage reference is a versatile and high-precision reference source, which is well-suited for many types of applications. It is an ideal choice for a variety of systems requiring accurate MCU cores, DACs and A/D converters. With its excellent temperature stability and accuracy, it is ideal for battery-powered instrumentation and portable medical equipment, automotive systems, industrial and telecoms products.
