The SPX385AS-L-1-2 is a precision voltage reference device from Infineon. It is part of Infineon\'s family of precision voltage references for a variety of applications. It is categorized as a PMIC - Voltage Reference.

Analog Devices precision voltage references are designed to deliver a constant, predictable voltage across its output terminal despite varying conditions. This type of device is vital for systems where a reliable and accurate power source is needed. Because the circuit is designed to produce a fixed voltage, the device is also ideal for systems where a very low output voltage is needed. This makes it a great choice for power supplies, precision temperature sensors, and other types of electronics.

The SPX385AS-L-1-2 is designed to meet the demands of users who require a voltage reference with the highest possible accuracy and reliability. It is certified for up to 3.45V, with a total error of less than 0.03%. It is also designed for use in high temperature conditions, with a rated temperature range from -40 to +85℃. The device is also capable of providing a 7µA low quiescent current and has an excellent supply rejection ratio (SRR) of 60dB.

In terms of its application field, the SPX385AS-L-1-2 can be used in a wide variety of electronics. It is suitable for use in medical devices, automotive components, audio equipment, and even in industrial process controls. It can also be used as a precision voltage reference in circuits such as transimpedance amplifiers and high-input-impedance amplifier circuits. Additionally, it can be used in high-voltage voltage detectors and as a shunt voltage band detector.

The SPX385AS-L-1-2 device has a simple and straightforward working principle. It is based on the principle of reverse-biased diode biasing. In this type of circuit, the diode is reverse-biased, so that a reverse current is passed through it. As the diode is reverse-biased, a voltage is generated at its terminals, and this is used as the reference voltage for the device. The reference voltage is then set using resistors, so that the device can meet the desired output voltage.

The SPX385AS-L-1-2 is an ideal solution for applications that require a precision voltage reference. Its low quiescent current and wide temperature range make it suitable for a variety of applications. In addition, it has an excellent output voltage accuracy and a good supply rejection ratio, making it a reliable choice for precision voltage references.
