PMIC - Voltage Reference

A voltage reference is a device or circuit that produces a fixed level of voltage regardless of the magnitude and direction of current flowing through it or across its terminals, unaffected by the changes in the surrounding environment, making it ideal for precision voltage comparisons and measurements required in analog circuits. The SPX385AM-L-2-5/TR is such a device, a very precise and robust low tube voltage reference.

It is capable of providing a very precise unit of voltage in an adjustable range of approximately 0.2V to 5.6V. The low temperature coefficient reduces the effects of power supply voltage drift on the accuracy of the reference voltage. The reference voltage output is within +/- 0.05% over its entire temperature range, making this device an ideal choice for precise voltage control and precise current sourcing applications.

The SPX385AM-L-2-5/TR operates in a wide variety of supply voltage ranges, making it very suitable for use in many different application fields. As long as the input voltage range is within 0.2V to 5.6V, it can precision voltage references for custom low voltage and micropower circuits, powering and stabilizing silicon photodiodes, or providing stable voltage references for instrumentation or measurement systems with no external signals needed. In addition, the device is also suitable for various automotive or industrial applications.

The working principle of the SPX385AM-L-2-5/TR is based on a bandgap voltage reference architecture. This architecture involves a two-stage amplifier, a voltage reference and a temperature-sensitive element. When power is applied, a small current is passed through the temperature-sensitive element and the amplifier amplifies this current to create a voltage reference. The voltage reference is then divided by the two-stage amplifier to form the reference voltage output of the device. The oscillator then ensures that the reference voltage is constantly monitored and adjusted.

The SPX385AM-L-2-5/TR is an ideal device for those seeking an accurate and precise voltage reference for a wide variety of applications. This device is capable of providing stable and reliable output voltages over a wide range of input voltages with minimal temperature drift, making it ideal for the most demanding analog signal processing applications. In addition, the device operates independent of external signals and is very easy to use and maintain, making it a popular choice for various application fields.
