PMIC - Voltage Reference

ZRC250A02 is a precision resistor 5-Terminal Voltage Reference Diode with an typically low temperature coefficient of 0.14 ppm/°C, which makes it ideal for high accuracy applications. Constructed with an optimized combination of a Schottky diode and a resistor, this device offers additional advantages such as high output impedance and temperature coefficient stability. It comes in a hermetically sealed ceramic T0-5 package with a 0.5mm mark to indicate the cathode. This voltage reference diode is suitable for high-performance applications such as digital voltmeters and regulators, as well as active front-end applications.

The ZRC250A02 is used for measurement and control applications that use low temperature coefficient voltage references in combination with operational amplifiers. In order to provide an exact reference voltage, a reference diode and a precision resistor are connected between two points that differ in voltage. The diode then maintains a fixed voltage between the points regardless of the current or temperature. The resistor, on the other hand, provides the base of the reference voltage. The two are connected as a voltage divider, which provides a voltage reference relative to the output of the operational amplifier.

The ZRC250A02 is designed to provide highly accurate reference voltages while also having a very low temperature coefficient. The temperature coefficient of the device is typically 0.14ppm/°C, which is lower than that of other types of voltage controllers. This makes the ZRC250A02 ideal for high accuracy applications, such as precision volt meters and regulators, as well as active front-end applications. The device also has a high output impedance, which helps to reduce errors caused by current noise. The ceramic T0-5 package of the device also helps to protect it from external noise as well as provide a stable environment for the reference voltage.

By taking advantage of the ZRC250A02\'s features, such as the low temperature coefficient and the high output impedance, engineers can create a voltage reference circuit that will guarantee accurate results in a variety of applications. For instance, in digital voltmeters and regulators, a precise reference voltage is necessary in order to achieve stable, repeatable readings. The ZRC250A02 also has applications in active front-end circuits, where it can be used to provide an accurate reference voltage for comparators and other components. Furthermore, it can also be used to provide a stable output signal in high-accuracy transducers or sensors.

In summary, the ZRC250A02 is an ideal device for a wide range of applications that require high accuracy and low temperature coefficient voltage references. Its advantages include a low temperature coefficient and high output impedance, which help to reduce errors caused by current noise. Furthermore, the hermetically sealed ceramic T0-5 package ensures that the device is protected from external noise as well as providing a stable environment for the reference voltage.
