AS431 series voltage references can be easily used in various applications due to their wide range of voltage, current, and temperature stability. The AS431BKTR-G1 is a low-power, 8-pin voltage reference IC designed for applications such as voltage-controlled oscillators, micro-controllers, LED driver circuits, digital displays, and transistor biasing. The device is constructed with an open-drain bipolar output structure, which makes it suitable for symmetric and non-symmetric voltage control.In addition to its flexibility, the AS431BKTR-G1 provides high accuracy and low power consumption. The device incorporates an external analog reference voltage enable input that can toggle the reference voltage output when triggered with a logic level signal. This reduces system power consumption and allows for precision regulation of output voltage levels. The device also features temperature coefficient values of 0.04%, making it ideal for applications where accuracy is critical.The AS431BKTR-G1 is designed to operate over a wide range of temperature and voltage conditions. It can handle operating temperatures of -40°C to +85°C, while its input and output voltage range is from -1.5V to +7V. With its user selectable gain settings, the device provides precise and stable output voltage under conditions of +/- 10% line and load variations. The device also features an output current capability of up to 25mA, making it suitable for powering low-current load applications.The AS431BKTR-G1 is ideal for low-power, low-noise voltage reference applications. It features a low size, low power, and low cost design that makes it suitable for a wide range of applications. The device is manufactured using a compact, 8-pin package with a built-in ESD protection that helps protect against electrostatic discharges.The core of the voltage reference circuit is the AS431BKTR-G1 voltage reference IC from Atmel. It contains a wide input voltage range, high accuracy, and low power consumption which makes it ideal for cost sensitive, low power applications. The IC consists of several components including a bandgap reference, series regulator, temperature compensator, and a current source. The bandgap reference is designed to generate a constant reference voltage. It is composed of two transistors, wherein one is an NPN transistor and another an even-arm, PNP transistor. The two transistors when connected in series, turn on and off at the same time and are thus opposite of one another. When a voltage is applied across the transistors, they create a reference voltage by combining the voltages at their bases and emitter. The voltage is held steady because the two transistors work in opposite directions and the gain difference of the PNP transistor is the same as the gain difference of the NPN transistor. As temperature changes occur, the difference in their respective gains remain the same, thus providing a constant reference. The series regulator then takes the reference voltage generated by the bandgap reference and regulates it to a stable, predetermined level. This is done by comparing the reference voltage to the feedback voltage and then adjusting the current supplied to the output to maintain the reference voltage. The temperature compensator helps to maintain accuracy and stability by compensating for the changes in the reference voltage due to temperature changes. It is usually composed of a voltage reference and temperature compensation circuitry. The circuitry compensates the reference voltage by using temperature sensors that measure the ambient temperature and then adjust the reference voltage outputs accordingly. The current source is the last component of the AS431BKTR-G1 and its main function is to supply the output current. The current source is usually composed of transistors and other components which work together to regulate the output current. In summary, the AS431BKTR-G1 voltage reference IC is an ideal low-power, low-cost solution for low-power, low-noise voltage reference applications. With its wide range of voltage, current, and temperature stability, it can easily be used in a variety of applications including voltage-controlled oscillators, microcontrollers, LED driver circuits, digital displays, and transistor biasing. Its low-power, small size, and high accuracy make it ideal for cost-sensitive applications. The device also features an external analog enable input that can toggle the reference voltage output when triggered with a logic level signal to reduce system power consumption. With its user selectable gain settings, it ensures a precise and stable output voltage under conditions of +/- 10% line and load variations.
